A healthy freshwater fish tank starts with quality water and safe accessories. By maintaining appropriate mineral and pH levels, and conforming to additional guidelines, you can ensure your fish live a long and happy life. Otherwise, the effects of metal toxicity, such as that created by aluminum dissolved in the water, can be devastating.
Chinese algae eaters, also known as sucking loaches, are semi-aggressive freshwater fish native to southeast Asia. Typically, Chinese algae eaters are kept in freshwater aquariums to control the spread of algae. At minimum, Chinese algae eaters require 30 gallons of fresh water. It’s also recommended to include plants, water and rocks in the tank because these fish love to hide among tank décor.
According to the University of California, freshwater is defined as water with a salinity of less than 1 percent. Freshwater habitats include ponds, lakes, rivers, wetlands and streams. These freshwater habitats are home to numerous species of animals and plants, including freshwater fish. The reproductive habits of freshwater fish depend on several environmental factors.
In many parts of the United States and the world in general, hard water and tap water are the same thing. Hard water just means that a given sample of water contains dissolved minerals, specifically various forms of calcium and bicarbonates. In terms of aquarium fish, this can be good or bad depending on the specific species of fish, since some fish prefer hard water and some prefer soft.
Live-bearing freshwater fish can be a fun addition to your home aquarium. If you buy fish from pet stores that house opposite genders in the same tank, you have a good chance of buying a pregnant fish, particularly if you select platys, swordtails, mollies or guppies. If you want to breed freshwater fish on your own, select both males and females from the same species and add them to your tank.
The Chinese algae eater does not come from China, nor is it a particularly effective algae eater. These fish actually hail from southeastern Asia, including Vietnam and Cambodia. Although they might eat algae as juveniles, they tend to get territorial and prefer fish food more and more as they age. Although distinguishing between immature males and females is all but impossible, it's not difficult to tell the gender of adults.
Needlefish and aquatic frogs do not belong in the same aquarium. Depending on the exact species of frog, the needlefish will either act as predator or prey. Additionally, some fish that go by the common name "needlefish" actually prefer salty, brackish water that does not suit aquarium frogs. Between predation and water chemistry, these organisms do not go together.
How long your freshwater fish can live without a filter depends on the species of fish and your aquarium conditions. Certain types of fish can spend their whole lifespans -- in some cases, a decade or more -- filterless; others won't make it through a single day. In addition, cleanliness, gravel and live plants determine whether some species can live without a filter.
The organisms we call fish include a huge variety of creatures. Fish belong to at least three classes -- for comparison, all mammals belong only to one. Within this vast diversity, fish reproduction varies wildly. Some species grow quickly to their full size, while others take decades. The reproduction of fish greatly influences how they interact with their environments, and it has conservation implications.
Sometimes, you can add shells to an aquarium, but it depends on the aquarium and the shell. Aquarium water will usually dissolve shells -- ruining your shells and causing problems with your water chemistry. However, the changes to your water chemistry can actually make the water better for very specific fish. And there are alternatives that can work in any aquarium.
Various species of danio grace the aquarium hobby, including the zebra, leopard and blue danios. The danio family will breed in captivity much more readily than most egg-laying fish. However, baby danios or fry hatch at a very tiny size and need some special care to survive to adulthood.
Mollies are a member of the livebearer family, a family of tropical fish that includes the iconic guppy. However, mollies are unusually delicate for this family, requiring more care and attention to detail. This extends to their life support equipment in an aquarium. Mollies need more than just an aerator in order to survive in the home aquarium.
GloFish are genetically engineered zebra danios, the first genetically enginnered fish to debut in the aquarium trade. These fish have a gene from coral that allows them to glow under certain types of lighting conditions. Despite their modifications, they still breed like regular zebra danios.
Setting up a freshwater aquarium can be difficult, time-consuming and expensive. It’s also very rewarding once it’s up and running. You’ll need to set up your tank days before you add fish, but as all aquarium species are not equal, they require varying tank setups as far as size, filters and lighting. Research suitable fish species for a new tank, decide which ones you want, then set up the appropriate equipment and bring them home.
The freshwater and saltwater angelfish belong to two very different groups of fish. Freshwater angelfish belong to the cichlid family and reproduce readily in the home aquarium. They take six months to a year to go from egg to adulthood. Marine angelfishes' reproduction is not as well understood.
A number of fish can glow. Some glow under normal light -- and would also appear bright under a black light. Others have the ability to fluoresce under ultraviolet light thanks to genetic engineering. Several mechanisms allow such fish to glow under black lights.
Silver mollies and silver dollars require an intermediate level of aquarium care. However, both require different aquarium water parameters. On top of this, behavioral differences make them poor tank mates. You should not keep silver dollars and any kind of molly in the same aquarium.
Pacus and freshwater angelfish make lousy roommates. While both fish come from the same general area and have similar preferences for water chemistry, the size difference between them makes these two types of fish a poor match.
Motoro stingrays are colorful freshwater stingrays. They are widespread in the Amazon basin, and their gorgeous, colorful spots make them among the most popular freshwater aquarium rays. However, they require a specialized aquarium and diligent care in order to thrive in captivity.
The suckermouth catfish, more often called the pleco, can share an aquarium with convict cichlids. But since various pleco species appear in pet shops, you must be careful to select an appropriate pleco in terms of demeanor and size. That little pleco from the pet shop can grow up to be a big fish in too small a tank.
Cichlids are some of the most brightly colored and interesting freshwater fish, rivaling the beauty of marine fish. Always do your research before bringing home any cichlids, however. Some cichlids can be very aggressive and should not be housed with other fish, while others are suited for a community tank.
The marigold variatus is a color variety of the variatus platy (Xiphophorus variatus). Generally, these fish are not particularly aggressive. However, they do have a few personality quirks you need to take into consideration when selecting tank mates.
Selective breeding has produced a dazzling array of platys. This, coupled with their low cost and easy-going demeanor, has made them common aquarium fish. However, you need to take care when selecting their tank mates.
Different types of fish have adapted to various temperature ranges. However, most common freshwater aquarium fish come from the tropics and prefer water slightly warmer than room temperature. Because of this, you'll need a heater for most freshwater aquariums.
High calcium levels are universally beneficial in saltwater aquariums, but high levels of calcium in a freshwater tank can be good or bad. Freshwater fish have diverse preferences for water chemistry, and you have to match your water to the fish you wish to keep.
Crystal red shrimp (Caridinia sp.) are small freshwater shrimp with brilliant red and white bodies. They can thrive in small desktop aquariums. They do require some specific care beyond more common freshwater shrimp and aquarium fish.
Cichlids are a popular type of freshwater tropical fish for home aquariums, and at least one group within the species, tilapia, are also farmed for food. There are hundreds of varieties of cichlids, though only a limited number are kept in home aquariums. Each of these varieties has its own growth characteristics, including growth rate and age at maturity. Some of the fast-growing species have been reported to add as much as an inch per month to their size. There are four main factors that will determine how fast cichlids grow, and how big they ultimately get.
The Super Red Empress, the protomelas taeniolatus, is a variation of Red Empress cichlid bred specifically to have bright red coloration on its body. Also known as the Spindle Hap, this tropical freshwater fish is favored by aquarium hobbyists for its beauty and easy care. In addition, with proper tank size, hiding places, water conditions and adequate male-to-female ratio, the Super Red Empress is easy to breed in captivity.
Aquarium salt is commonly used to treat sick and injured freshwater fish. Salt encourages the healing of wounds and kills off external parasites. It is also used to prevent nitrites from entering a fish's body via the process of osmosis. Freshwater fish can tolerate a low level of salt, but not as much as a salt water-dwelling fish would. Unlike sea water, which contains a high concentration of dissolved salt ions, fresh water has a low to little concentration of the substance.
Texas has only one native species of cichlid, called, unsurprisingly, the Texas cichlid (Herichthys cyanoguttatus). In fact, it is the only cichlid in the United States. However, the species comes in two varieties, which need similar housing and care. The main varieties are the red Texas cichlid, which is a hybrid, and the blue Texas cichlid. A third fish goes by the same name; this is the green Texas cichlid (Hericthys carpintis), which is actually a completely different species, originally from Mexico. Note that aquarium suppliers often misidentify their fish, so always check a guidebook before purchase or, preferably, buy…
Guppies are one of the most proliferate fresh water fish you can buy. Most female guppies breed every 30 days and can give live birth to as many as 200 fry in a single liter. In large tanks it’s possible for multiple guppies to be pregnant at the same time. Separating pregnant guppies from each other and from other community fish is necessary to ensure fry grow into adult guppies, rather than become food for mom or other tank-mates.
As the name suggests, peacock cichlids (genus Aulonocara) come in vivid colors, especially the males. Females and young males have muted colors, but adult males have nearly neon scales in vibrant yellows, blues, golds, reds and oranges, attracting aquarium owners as well as the target audience of females. These species are native to the same huge lake, Lake Malawi in Africa, and are relatively straightforward to care for.
Water quality is the most important element in keeping a successful aquarium, as well as the most challenging. It must be maintained in a freshwater fish tank to ensure the health of your fish. Water's pH levels relate to its acidity, which is measured on a scale from 0 to 14. Freshwater pH levels of 0 to 6.9 are acidic, 7.1 to 14.0 are alkaline and 7.0 is neutral. Water with high pH levels has high mineral contents. Low and high pH levels create stress in fish, harm their color and growth and may be fatal. Most freshwater tropical fish…
As one of the most popular aquarium fish choices, guppies add a splash of color to many freshwater tanks. Guppies have many distinguishing features and attract fish enthusiasts with their wide array of markings and shapes. With new guppy breeds arising each day, these physical traits help to sort them by shape, color and gender. The small size, great diversity and ability to coexist in large groups make guppies an easy fish to maintain and enjoy in aquariums.
Scientifically named Pterophyluum scarlare, the angelfish is one of the most popular fish kept as a pet, reports “500 Freshwater Aquarium Fish.” Native to the Amazon River in South American, these fish like warm waters and are highly carnivorous. Providing your pet angelfish with a habitat and diet similar to its wild ancestors will give it a pampered life.
Adding salt to a freshwater aquarium does not make it a salt water tank, but small amounts of salt are beneficial to the fish and will kill bacteria. Most organisms naturally contain salt ions, with fish having higher concentrations than bacteria. If the surrounding water has a higher salinity than the organisms in it, a process known as osmotic pressure will leach fluids and salt from the organisms, dehydrating and killing them. The simple cell organisms that make up bacteria die in a tank containing small amounts of salt, but many fish will thrive in the same environment.
Guppies require very little maintenance, making them a popular pet choice. They can survive a wide range of pH, salinity, and other water conditions. They do well in a variety of tank sizes and unless they are very crowded, do not mind sharing the tank. Although guppies are very easy to care for, keeping them healthy does require some thought, and a little aquarium salt goes a long way toward that goal.
Ichthyophthirius multifilis, or Ich, is a parasitic infection that affects aquarium and pond fish. It is also known as white spot disease, because it causes white dots all over the body of an infected fish. Ich can infect cold water and tropical freshwater fish, and can infect fish tanks through the addition of new fish, live plants and live food. In addition to white cottony body spots, infected fish may seem lethargic and clamp their fins. If left untreated, ich can prove fatal to your pet fish. Use natural and chemical treatments to immediately treat your freshwater fish tank because…
Angelfish are one of the most popular additions to a fresh-water aquarium because of their color, hardiness and affordability. If you decide to buy a mated pair of angelfish with the intent of raising baby angelfish – called fry – you'll need to monitor their growth into adulthood over a period of about two months, taking extra care with their diet. Angelfish reach adulthood between six and eight weeks of age and can then be sold to retailers.
Contrary to the name, Peacock Bass are not actually bass but are part of the cichlid family. This species of fish is found in northern South America and southern Florida. Certain fish enthusiasts choose to keep them in aquariums. However, Peacock Bass are one of the more difficult fish species to maintain in an aquarium and require a knowledgeable aquarium keeper to properly care for them.
Current trends indicate a burgeoning public interest in processes foods go through before they find their way to the dinner table. For the home owner opting for a more self-sufficient, homegrown lifestyle, a garden pool is an excellent facility in which to raise trout—a delicious, healthy and lean source of nutrition.
Due to their sociability and non-aggressive nature, Corydoras catfish are commonly found in home aquariums. They are a small freshwater fish that can tolerate a variety of water conditions, as long as the nitrate levels are low. They are bottom feeders and not very picky ones, at that. They live up to 10 years, although some have survived longer than 20 years in captivity. Maintaining proper water temperature and pH levels, and feeding them twice a day, will keep your Corydoras catfish healthy for years to come.
There is a variety of freshwater and saltwater shrimp that you can keep in your home aquarium. Adults may range in size from 1 to 4 inches long, depending on the species. Most freshwater shrimp are hardy and go well with other peaceful shrimp in your aquarium, but you must make concessions for them so they feel just comfortable as your other fish. Making your aquarium a proper home for shrimp includes providing logs and lots of hiding places and climbing surfaces as well as moss and a cave.
Rainbow trout are cold-water fish native to North American streams, rivers and lakes west of the Rocky mountains. These fish generally weigh about 8 lbs. and are blue green with a pink streak on their side. Rainbow trout are often kept in man-made and natural fish ponds and lakes. Since they are already accustomed to the North American environment, these trout are easy to care for in captivity and only need a few basic requirements to sustain them.
Grey striped barbs, more commonly referred to as tiger barbs, are an active schooling fish that do best in groups of five or more. They are a semi-aggressive fish known to be fin nippers and may pick on fish who are sick or injured. They thrive in a well-planted and heated tank.
Leopard corydoras catfish are small fish, growing only to between 2 1/2 and 3 inches long. They have a distinct brown or gold coloring, overlaid by dark brown or black spots or stripes, which gives them their name. These fish are very peaceful, so they work well in many freshwater aquariums. These fascinating fish are easy to keep, even for the beginner aquarium enthusiast. However, some leopard catfish can be sensitive to changes in the aquarium water, so knowing how to care for them is essential.
The blue lobster crayfish, also known as the blue lobster or the blue crayfish, is a type of crayfish that, as its name suggests, is a startling and beautiful shade of bright blue. These small, lobster-shaped creatures can grow to between 2 and 8 inches long, and may live for up to five years. Blue lobster crayfish can be fascinating to watch as they move and hunt. They can also be aggressive toward other aquarium inhabitants. Due to this behavior, and their size, it’s best to care for just one blue crayfish in an aquarium.
Black upside down catfish, also known as giant Asian upside down catfish, are an unusual and fascinating species. As their name suggests, these catfish spend much of their time swimming upside down, in order to skim food off the surface of the water. These fish are somewhat similar to more common types of upside down catfish, but they can grow much larger and tend to be more aggressive. Because of their size and temperament, black upside down catfish are excellent fish for advanced aquarists.
With their brilliant colors and frilly tails, guppies might look like fragile exotic fish, but they are actually adaptable and reasonably easy to raise. Provided their basic needs are met, guppies tend to thrive in a home aquarium. They are a good choice for people new to aquariums, as you have a high chance of successfully rearing them. Provide a suitable habitat and diet for young guppies and they should live for up to three years, possibly longer. Breeding is also likely once the fish mature.
Crayfish are crustaceans that live in freshwater. They look like small lobsters and are often seen in streams and creeks with fresh running water. Crayfish prefer dark and cool places, most often hiding under rocks and other shelter during the day. Like most animals, crayfish reproduce sexually.
Tetras come in several varieties, including Cardinal, Neon and Glow Light. Because tetras are schooling fish, include at least five tetras in the aquarium, and leave enough swimming space for them -- about a 15-gallon tank size. If you have male and female tetras in an aquarium, you may end up with tetra eggs. While you may not be able to pin down exact dates, there are a few ways to identify females and determine if they will soon be laying eggs.
Rainbow sharks are freshwater creatures originally from Thailand. Though small in size, they can be aggressive so you should be careful about what fish, if any, share a tank with a rainbow shark. Rainbows are territorial, so they need caves and places to hide in their tanks. If they feel like other fish are invading their space, they will chase them. However, fish that also enjoy planted aquariums, require similar water temperature, typically live in schools and are of a peaceful temperament usually live will with rainbow sharks.
The Gasteropelecidae hatchetfish family are considered the true flying fish. Hatchetfish are the only fish that move or "flap" the pectoral fins to aid them as they leap from the water to catch insects. Marbled hatchetfish are the easiest to breed within an aquarium setting. Hatchetfish are positive community fish, however being surface feeders, flying insects are required for food. Add live plants to hatchetfish tanks, as the fish will lay eggs within them. Provide an ultimate spawning environment within a tank dedicated only as an environment for breeding hatchetfish.
Day Glow tetras are also called Glowlight tetras. They are in the same family as other tetras and are egg layers. While they are prolific in the wild, Day Glows are not as easy to breed in captivity. They're found naturally in the wild in Guyana, South America. For successful breeding, water conditions must match those found in their natural tropical habitat.
A common killer in aquariums is excessive nitrite levels. Nitrite is a byproduct of fish excretion and is produced by the decay of organisms or food. High nitrite levels are toxic to fish and can easily wipe out a newly established aquarium. Keeping nitrate levels under control requires promoting the growth of beneficial bacteria to break down ammonia and nitrite into less harmful substances. Regular water changes can also reduce the proportion of nitrite in the water.
There are two species of fish that are sold as "jellybean kissing fish" in aquarium and pet stores. The first fish is a known as a kissing gourami, or Helostoma temminkii, while the second fish is hybrid fish called a blood parrot. Both fish types have mouths that look like they are blowing kisses. Though both types of fish can become aggressive when certain factors, such as water quality and overcrowding, existing in the aquarium, blood parrots are more likely to eat the tank's other fish.
The parrot fish is known for its distinctively shaped mouth, which really does resemble the beak of a parrot. Parrot fish are actually cichlids, but unlike some other breeds they tend to be rather peaceful in the community tank. You can house parrot cichlids with fish like silver dollars, danios, barbs and with some other species of cichlids as well.
Guppies are common aquarium fish that originate from the freshwater streams and lakes of South and Central America. There are nearly 300 different species of guppies found in the wild. They eat mosquito larva, so they are considered to be very helpful in keeping levels of malaria low. Many enthusiasts choose to include guppies in their tanks because the fish breed prolifically and are extremely colorful.
Saltwater fish and freshwater fish can both be affected by parasites. Parasites infect the intestinal system of freshwater fish, using them as a food source during all or most of their life cycle. Although the parasites prosper from this interaction, the freshwater fish suffer. Parasites can lead to blood loss, destroy tissue and cause secondary infection. The parasites strip freshwater fish of their nutritional needs, causing them to starve and eventually die.
There are many variables to consider with raising catfish in aquariums. There are scavenger catfish that feed only on algae and predatory catfish that will eat anything that they can swallow. Some catfish are small while others are enormous. All catfish will require appropriately sized tanks, proper substrates and sufficient food, and these conditions also vary depending on the species in question. Despite these challenges, there are advantages to indoor catfish keeping that make it worthwhile, such as avoiding the need to winterize the catfish and protecting them from external predation.
Red-tailed sharks (Epalzeorhynchos bicolour) belong to the minnow and carp family. These fish are well-suited to freshwater aquariums. Reaching a length of up 6 inches, red-tailed sharks must be housed in a 30-gallon or larger tank. Red-tailed sharks can be aggressive both to each other and to similar-looking species. For this reason, take care when adding this species to your tank or choosing tank mates for it. Otherwise, they have much the same requirements as most tropical freshwater aquarium fish. Given the right habitat and care, an individual may live for 15 years or more.
Blue catfish are among the largest freshwater fish in the world. They are aggressive, protective of their offspring, and will consume almost anything that is smaller than they are. While hardy and adaptable, raising these huge fish in captivity is very difficult, as they can grow over 5 feet long and weigh well over 100 pounds. Anyone wishing to raise a blue catfish requires either a very large aquarium or a deep, temperature-stable pond to keep them in, and the expense in feeding even a single specimen can be quite large.
Mollies are simple fish to keep alive and will breed in a variety of conditions, which makes them perfect for the first time fish keeper. A mollie that has bred will usually produce its young in about 30 days after the breeding takes place. You can help the mother by feeding it plenty of mollie fish food and protect the fry by placing them in a breeding net or a separate tank away from other fish.
Neon tetras (Paracheirodon innesi) are a very beautiful and easily cared for freshwater fish. They are best kept in groups of at least five since they like to swim together in groups or shoals. They are originally from South America and are usually found in the Paraguay River basin, the Rio Taquari, the Pantanal of Mato Grosso do Sul and Brazil. They are identifiable by their red and electric blue stripes. They are omnivorous and will eat flake food, bloodworms and small crustaceans. They are difficult to breed in captivity because this calls for maintaining proper water conditions in the…
Gourami are freshwater fish that are extremely susceptible to constipation. One cause of constipation is a spleen or intestinal iridovirus. Currently, there is no cure for this virus in fish. Fish owners should not jump to conclusions, however. Less harmful swim bladder conditions and general stomach upset similar to that in humans, can also cause constipation in gourami..
Angelfish are freshwater fish that originate from the rivers of South America. They are a popular fish to have in fish tanks due to their varied colors and normally non-aggressive natures. Thanks to the fact that they are native to both the Rio Negro, with its soft, acidic waters, and the Amazon River, with its moderately hard, less acidic waters, angelfish can adapt to both types of water and survive well in aquariums. Over the years many different domestic breeds have been created.
Tilapia are a freshwater fish raised for their meat worldwide. These delicious fish are a popular treat, especially in East Africa. Many aquaculturists are turning to tilapia to make a tidy profit raising them and selling them for their meat. You too can easily raise tilapia as a self sustaining food source in your backyard with a large pond, water and the help of some chicken fertilizer.
If you are considering adding blue crayfish or any crayfish to your aquarium, you must assure that your aquarium has the right environment for the crustaceans, or the creatures won't survive. Your tank should be 10 to 15 gallons in size for one crayfish. Keep in mind that crayfish are territorial and they will kill any other crayfish that venture into their space. Crayfish are aggressive and will nip the fins of fish in the tank.
GloFish are a type of zebrafish that have a brilliant, fluorescent glow, and are a great addition to aquariums in homes, offices and classrooms. They were originally bred by scientists to help detect polluted water. The goal was for the GloFish to flash fluorescent colors when in contaminated waterways, and display no fluorescent colors when in clean water. Although scientists have not yet been successful in achieving this, the results are brightly-colored flourescent fish that are entertaining to watch. When observed under black lights in a darkened room, the colors are particularly brilliant and appear to glow.
Guppies are small, tropical fish that come in a myriad of colors. Fancy-tailed guppies are no more difficult to breed than regular guppies. Like other members of the Poeciliidae family, fancy-tailed guppies give birth to live young. Females are larger than males, and a mature female can bear 24 to 48 fry every month.
In the context of aquarium fish, the term "livebearers" may refer to any fish that give birth rather than lay eggs, but it is most associated with a few common tropical fish. Mollies, guppies and platies and swordtails are all relatively easy to keep and breed. These livebearers have similar tank requirements and a basic set-up is much the same for all. You need a moderately spacious, heated tank with a filter, gravel and aquatic plants.
Mollies are often the first fish purchased by aquarium enthusiasts when they plan a community fish tank. Placid mollies get along with many other types of fish and come in a variety of hybrids with differences in fin shape, color and size. Mollies are prolific breeders and can live up to three years if given proper care.
Kenyi cichlids are aggressive freshwater fish that originate from Africa. They are members of the Mbuna family of cichlids, and are enjoyed by aquarium enthusiasts for their various colors and easy care. Though they are not community fish, Kenyi cichlids usually do well in schools of their own species. A combination of at least four females to one male will result in a harmonious environment ideal for reproduction. Aquarium hobbyists who want to breed Kenyi cichlids will be successful with the proper tank conditions.
Some people consume salmon eggs as part of their meals. Consequently, salmon eggs must be disinfected to prevent the transferring of bacteria or viruses to humans. The federal government and many state governments place the responsibility of disinfecting salmon eggs on the distributors of the product. Some states even adopt strict disinfecting policies to ensure uniform standards. The Michigan Department of Natural Resources is one such state agency that has established strict disinfectant standards and provided a guideline for disinfecting salmon eggs.
Plecostomus or "plecos" refers to both a specific species of freshwater catfish commonly seen in the pet trade and to a group of freshwater catfish that share similar body structures and habits. All of these species originally are from South or Central America. In captivity, plecostomus live at the bottom or sides of tanks, cleaning algae off decorations and walls. Although their main diet is algae, they need a variety of fish foods to remain healthy.
Hydra are freshwater relatives of coral and jellyfish. They attach to plants or other surfaces in the tank and extend their tentacles, waiting for small food items like baby fish or baby brine shrimp to wander into their grasp. These food items are stung by the tentacles and reeled in to the hydra's "mouth," which is at the top of its stalk-like body. While you can maintain a tank of hydra, they normally are seen as a pest animal. There are several natural methods you can employ to get rid of the hydra in your tank without having to resort…
The firemouth cichlid (Thorichthys meeki) will breed in the home aquarium. If you can raise the fry to about 2 inches in length, you can sell or trade it to a local fish store. To breed this species of fish, you need an aquarium of at least 30 gallons with plenty of hardy plants, soft sand substrate and stacked rocks to provide hiding places. The water's pH should be 7.0 and the temperature should be around 73 degrees Fahrenheit. The fish may spawn several times a year if well-fed and the water is kept clean.
Salt can be used in fresh water tanks for live bearers, gold fish and other scaled fishes. When purchasing fish for your tank, ask the seller if the fish you select can tolerate salt. If you have fish that are not salt-tolerant, but are familiar with how salt can benefit fresh water fish, there are alternatives that can be purchased at most fish supply stores or from your veterinarian that will achieve similar results.
Peacock bass (Cichlia ocellaris) is a species of cichlid native to the Amazon river and its tributaries. When sold as aquarium fish, they are usually about 2 inches long; however, the fish can grow to 2 feet in length and up to 5 pounds and need an aquarium 70 gallons or larger. Some sources say that peacock bass have not been observed spawning in an aquarium. However, some aquarists on various forums have pictures and videos of their peacock bass spawning. Most of the breeding peacocks seem to be accidental rather than deliberate attempts by aquarists to breed the fish.…
The plecostomus, or "plecos" fish, are voracious algae eaters. Some species can become quite large, while others will remain a few inches long. They are great additions to the community aquarium. Plecos are tropical freshwater fish and need water temperatures of about 75 degrees. Some species can be kept in planted aquariums, but they need to be well fed to prevent them from eating the plants. Encouraging algae growth in the aquarium is one way to provide a natural food source for plecos.
The serpae tetra is a widely available fish that is ideal for beginner aquarium hobbyists. It's a hardy species that can survive varying water chemistries. It also makes a good addition to a community tank, provided several tetras are kept at once. The serpae tetra does not have any demanding care requirements.
Freshwater gars originate from Asia and are scientifically known as Xenentodon cancila or Needlenose Gars. They grow to be about a foot long and are carnivorous fish. Freshwater gars also like to school and can tolerate both brackish and fresh water. There are several types of freshwater gars, but most are too large for any tank, and the Needlenose gar is the most common gar domesticated.
The nitrogen cycle of a freshwater aquarium involves converting fish waste into ammonia and nitrates. In an ideal freshwater environment, a nitrate test kit would show a nitrate level of no more than 20 parts per million. Levels that read higher than this could cause excess stress to your fish, which could result in disease or death. To date, there are no additives on the market that claim to lower the nitrate levels in aquariums. The only way to truly remove them without damaging your aquarium's delicate ecosystem is through a partial water change and by adding live plants.
Raising Angelfish fry can be challenging. Angelfish fry begin swimming after about a week and are ready to begin feeding. Your survival numbers of fry may be lower as time passes. As the Angelfish mature and look more like their parents, however, their survival rate becomes more stable and less special care is needed. .
Fish have an aquatic respiratory system that isn't the same as those of land animals. Fish can breathe under water which marine mammals, such as whales, can't do as they have to make frequent trips to the surface to take a breath. Fish have gills, which are their breathing organ. The gills are feathery and thin sheets of membrane that contain air vessels. Oxygen passes through the gills for fish to breathe.
Mysis shrimp, Mysis relicta, are a small, freshwater shrimp species found in the Great Lakes region of the northern United States and Canada. These shrimp are an important part of the food chain in their natural habitat, where they feed on plankton and are consumed by fish. Because mysis shrimp are consumed by many game fish, they are used as lure models for fly fishing. They are also commercially raised and harvested as a food source for aquarium fish, due to their high protein and nutritional fatty acid content.
Corydoras catfish (or cory cats) are one of the easiest fish to breed in a home aquarium. Fish fry can usually be sold or traded to a local fish store once they are large enough and are eating prepared foods (such as sinking pellets and flake food). Control of the water parameters (pH, temperature, ammonia, nitrite and nitrate levels) is critically important for the health of the adult and fry corys.
Red-bellied pacu are often chosen as an alternative fish to piranhas because of their similar appearance and vegetarian nature. Unfortunately most people who purchase these fish don't realize the size that they grow to and a what rate that growth occurs. Pacu routinely reach sizes of 30 inches or more, and exceptional specimens can weigh in at over 60 pounds. If kept in a large enough tank, these fish are amazing displays and are smart enough to recognize their owners, even performing for food.
Goldfish absorb oxygen from the water ("breathe") through their gills, like many other types of fish. Gills work differently than the lungs of air-breathing animals, but the goal of absorbing oxygen into the blood is the same for both gills and lungs. Goldfish need oxygen to live and they have to remove oxygen molecules (O2) from the water. Although the water molecule (H2O) contains oxygen, the hydrogen atoms prevent the fish from using water as a source of oxygen.
Removing existing aquarium water and adding freshly prepared water helps dilute harmful chemicals, such as nitrate and phosphate, and replenish trace minerals. For best results, you should change 20 percent of the total water volume of the aquarium every week. This means if you have a 50 gallon aquarium, you should replace 10 gallons of aquarium water with freshly prepared water every week. The freshly prepared water should at least be dechlorinated, and filtered water is generally better. Setting up a system to automatically change the water takes some effort. If you have a continuous supply of fresh water, this…
Loaches are wonderful freshwater aquarium fish, but like other bottom-dwelling fish it can be hazardous to clean the gravel with a siphon. If the loaches hide under the gravel or between plants or decorations, you run the risk of sucking the fish through the siphon. This can seriously stress or even kill the fish. There are a few tips for how to help protect the fish from the siphon and what to do if you accidentally catch a loach.
Dividers, also called baffles, in aquarium and pond filters let you add different filtration media to different sides of the filter. This in turn lets you better control and customize the filtration system to your needs. Some pond filters use the same filtration strategy as aquarium filters: A mesh particulate filter over plastic or ceramic balls (bioballs). Adding a divider allows you to add other filtration such as activated carbon, chemical reactants, such as those that remove phosphates, and sediment filters.
The common name "pleco" is given to sucker-mouth catfish in the taxonomic family Loricariidae. There are several small and medium-sized species that can be kept in a home aquarium. The are called sucker-mouths because their mouths are shaped like suction cups and you will often catch them stuck to the side of your tank. Plecos are algae eaters, scouring the aquarium for any excess growth. They enjoy caves in their tanks, which they can retreat to if startled or use for breeding purposes.
Freshwater shrimp are good additions to home aquariums because of their ability as scavengers, and their ease of care. Because freshwater shrimp come in many varieties, it is essential to be aware of the species you purchase and what their specific needs are. With a little time and maintenance, freshwater shrimp can provide a fun and enjoyable home aquarium experience.
Silver hatchetfish are found in the waters of South America including those in Brazil and the tributaries of the Amazon. These fish, though typically silver or white in color, can also exhibit iridescent shades of green and blue. The silver hatchet fish is a peaceful species that make excellent community fish. These fish are a joy to keep but they can be difficult to breed. Very few instances of successful captive breeding of these fish have been documented but if you follow the proper procedures and try for yourself you may get lucky.
Crayfish (also called crawfish, crawdads or mud bugs) can be kept in captivity in several different environments. The scale of the captive habitat will vary with the animal's size and the purpose of the habitat, but there are some similar elements between them. For example, crayfish kept as pets will have different habitats than those kept for aquacultured food.
A tadpole consists of the larval stage in the life cycle of a frog or toad. Tadpoles are amphibians that consume algae and plant material. Because of their size and location, many tadpoles are prey victims of various reptiles, fish, mammals, amphibians and birds. Unfortunately, there is not much tadpoles can do to survive the attacks of their predators.
Bettas, also called Chinese Fighting Fish, are known for their brilliant colors. Betta fish are relatively easy to breed in captivity, but it is not always easy to predict the color of the offspring. Unless you are familiar with genetics and are willing to experiment, you may never succeed in producing betta fish with the color combination you desire. Take the time to learn about basic genetic principles and determine what combination you want to achieve before setting out to breed your betta fish.
The tiger trout is a kind of fish that is born due to the breeding of male brook trout with female brown trout. The hybridization process occurs when the male sperm is fertilized with the female eggs. The sterile game fish is known scientifically by the name of Salmo trutta x Salvelinus fontinalis.
Rainbow sharks are popular aquarium fish that live in freshwater. They are not sharks, as their name suggests, but are territorial minnows native to Thailand with a small, sharklike dorsal fin. Rainbow sharks have mouths that face downward for bottom feeding. The vivid red or orange coloration of their fins makes them an attractive complement to an amateur fish tank. Rainbow sharks are an active fish and require certain tank conditions to flourish.
