We had two texas cichlids, two convict cichlids, and a green terror in the tank. the convict cichlids laid eggs but the texas male ate all of them. then once the texas cichlids laid eggs the male killed all of the other fish including his mate and now we only have the texas cichlid male and about 200 babies.
if anyone is interested in buying them i live near janesville, you would have to come and pick them up but if ur interested u can e-mail me
Where do you buy bubble eye fish Terry Murray

Where do you buy bubble eye fish Terry Murray
I am looking for a source of several hundred cichlids. They will be research animals, not pets. I am doing a study looking at male mate choice and fecundity based on selection of female in relation to the size of her orange 'patch'. The animals will not be required all at once (actually it is preferable that they are not all at once) but we will need about 50 at a time. We need fish which are greater than 1 inch in length and about twice the number of females to males.
If anyone has any suggestions! Kristy
The Red-bellied Piranha Pygocentrus nattereri has a long history with aquarium keepers. It has been kept by aquarists for well over 60 years. This species is also one of the most commonly found piranhas, with a wide distribution throughout the Amazon and Orinoco Basins in South America. Members of the Pygocentrus genus are considered "true piranhas," and the Red-bellied Piranha is perhaps the most handsome of the group.
The adult Red-belly Piranha has gorgeous coloring. Its back is a steel gray, and the rest of the body is a silvery gold with a bright orangish-red to red throat, belly, and anal fin. This large piranha reaches up to 13 inches (33 cm) in nature, though it is smaller in the aquarium. In the wild, they are found in groups of 20 or so fish. These shoals provide a pack for hunting as well as individual protection from predators. This piranha is considered one of the most ferocious of the piranha predators.
Though Red-bellied Piranhas are not picky eaters and are quite hardy, they are best kept by experienced fish keepers. Red-bellied Piranhas are fascinating and beautiful fish, but you can't hold or pet them. They are not affectionate, and owners must be extremely careful when handling them. These fish have sharp teeth and an aggressive/defensive nature. Most Piranha bites are sustained when the fish are being handled, though that's not to say a hungry fish is never dangerous.
Red-bellied Piranhas are highly predacious and not candidates for a community tank. They can be kept singly but are actually one of the easier piranha species to keep in a group. They can be combined with other Pygocentrus species as well as other Red Piranhas. In a group, some of their natural behaviors will show if they are kept under proper conditions. However, even in an established group, aggression and cannibalism amongst piranhas is not unusual. Generally, the largest, most aggressive fish will be dominant. It will demand the best spots in the tank and be the first to feed. Any perceived competition by another fish will be quickly corrected with aggressive behavior of chasing and even inflicting wounds.
A single fish requires a minimum tank size of 40 gallons, but a group requires a much larger aquarium. These big, messy feeders need ample filtration and regular water changes to handle the bio load their feeding puts on the tank. They are generally less skittish and shy when they live in a tank with plenty of hiding places and dimmed lights. Keeping them in a school of 4 or more will also help overcome their timidity.
The Red-bellied Piranha Pygocentrus nattereri (previously Serrasalmus nattereri and Rooseveltiella nattereri) was described by Kner in1858. There is much discussion and debate on the true taxonomy of this fish, so its scientific name may change in the future, but currently it is considered P. nattereri. The species is not listed on the IUCN Red List. Other common names this species is known by are Red Belly Piranha, Red Piranha, and Natterer's Piranha. A few variants in color have also led to the occasional use of such names as Ternetzi Piranha, Super Red Piranha, Snakeskin Piranha, and Gold-dust Piranha.
Red-belly Piranha are found across a wide geographical range in South America, including Venezuela, Brazil, Peru, Guyana, Bolivia, Paraguay, Argentina, Colombia, Ecuador, and Uruguay. They live in the Amazon River Basin as well as in the basins of the Paraguay, Paraná, and Essequibo Rivers. They also inhabit the coastal rivers of northeastern Brazil and numerous other small water systems.
They inhabit all sizes of running waters, from rivers, to tributaries and creeks. They also are found in larger bodies of water including lakes, pools, flooded forests, and the Pantanal wetlands of southwestern Brazil. These schooling piranha are generally found in groups of 20 to 30 fish.
The Red-bellied Piranha is an opportunistic omnivore with a widely varied diet that includes fish, both whole and in pieces, fish fins and scales, insects, snails, and plants. Though they are scavengers, they are also full-blown predators and will actively give chase to their prey.
Scientific Name: Pygocentrus nattereri
Social Grouping: Groups - They are generally found in schools of 20 to 30 fish.
IUCN Red List: NE - Not Evaluated or not listed
The Red-bellied Piranha can get up to 13 inches (33 cm) in length in the wild, though in captivity they are generally smaller. A lifespan of 10 years is normal, but a few have lived for over 20 years.
These fish have powerful bodies that are high, thick, and laterally compressed. Like all piranhas, they have a keel-like edge that runs along the upper body from head to dorsal fin and along the belly on the lower body. Members of the genus Pygocentrus are all recognizable by the convex shape of their head and massive, bulldog-like lower jaw. With a large, powerful tail and a streamlined body covered with tiny scales, they are very fast and agile swimmers. They also have a small adipose fin between the tail and dorsal fin, a characteristic of all Characins.
The Red Belly Piranha is gorgeous in its adult coloring. Body colors can be variable, but mostly the back is a steel gray and the rest of the body is a silvery gold with a bright orangish-red or red colored throat, belly and anal fin. It has large black spots on the sides, though they often fade with age, and it sparkles with many shiny scales. In its juvenile form it is more silver colored with dark spots.

Some individuals have such intense gold-speckling that they are sometimes called Gold-dust Piranha. There are also two similar species sometimes available in the aquarium hobby. These include the San Francisco Piranha Pygocentrus piraya, which is a yellow-bellied species. Another is the Black Spot Piranha Pygocentrus cariba, which still has the red on its throat and belly, but has a silvery colored body accented with a strong black spot just behind the gill.
Size of fish - inches: 13.0 inches (33.02 cm) - These fish get up 13 inches (33 cm) in the wild but are usually smaller in captivity.
Lifespan: 20 years - They generally have a lifespan of about 10 years in captivity though they have been known to live for over 20 years.
Fish Keeping Difficulty
Though Red-belly Piranhas are not picky eaters and are quite hardy, these predacious fish are best kept by experienced fish keepers. You can't hold or pet them, and they are not affectionate. Owners must be extremely careful, especially when handling them.
Aquarium Hardiness: Moderately Difficult - Although these fish are fairly hardy, aggression often leads to injury, which can shorten the lifespan of this fish in the home aquarium.
Aquarist Experience Level: Advanced - Owners must be extremely careful, especially when handling them.
Foods and Feeding
Red-bellied Piranhas are carnivorous omnivores. In the wild, their diet is variable, including fish, both whole and in pieces, fish fins and scales, insects, snails, and plants. In captivity, they can be trained to eat whole dead fish, such as frozen silversides and lancefish, as well as a variety of other meaty foods such as prawn, mussels, and fish flesh. They will eat live foods such as feeder fish, earthworms, and river shrimps, but this is not really desirable as it puts a huge pollution load on the aquarium.
Diet Type: Omnivore
Flake Food: No
Tablet / Pellet: No
Live foods (fishes, shrimps, worms): Some of Diet - These types of foods are not desirable as they can quickly foul the water and place a large bio load on the aquarium.
Vegetable Food: Some of Diet
Meaty Food: Most of Diet
Feeding Frequency: Daily
Red-bellied Piranhas are big, messy feeders, so they need ample filtration and regular water changes to handle the bio load. Water changes of 30 to 50% every other week are recommended.
Water Changes: Bi-weekly - Do a 30 to 50% water change every other week.
Red-belly Piranha will swim in all parts of the aquarium. A single specimen requires an aquarium of at least 40 gallons, but a group will require a much bigger tank. These apprehensive fish will be less timid if kept in a school of 4 or more. Because they are very messy feeders, they need strong filtration and a moderate water flow to keep up with the bio load.
These rather timid fish will be less skittish and shy in an aquarium with a lot of hiding places. However, they also need plenty of swimming space. This omnivorous species has been reported to eat some aquarium plants. Adding bog wood and placing plants around the perimeter will offer some cover to help them feel at home while leaving an open area for swimming. Provide a substrate of sand or fine gravel, and use dim lighting.
Minimum Tank Size: 40 gal (151 L) - A 40-gallon aquarium is fine for a single fish, but a group will need an aquarium of 100 gallons or more.
Suitable for Nano Tank: No
Substrate Type: Small Gravel
Lighting Needs: Low - subdued lighting
Temperature: 74.0 to 82.0° F (23.3 to 27.8° C)
Range ph: 6.5-7.5
Hardness Range: 4 - 18 dGH
Water Movement: Moderate
Water Region: All - These fish will swim in all parts of the tank.
This fish sometimes appears surprisingly skittish in the home aquarium. In the wild, the Red-bellied Piranha swims in schools of 20 to 30 fish. These ferocious predators are definitely not candidates for a community aquarium. They can be kept singly but are actually one of the easier piranha species to keep in a group. They can be combined with other Pygocentrus species as well as other Red Piranhas.
A group should contain at least 4 fish. Be warned that even in an established group, aggression and cannibalism are not unusual. A school of piranha is incredibly hierarchal and there will be a clear chain of command. Generally, the largest and most aggressive fish will become dominant. This fish will claim the best spots in the tank and be the first to feed. A challenge by another fish will result in aggressive behavior such as chasing and even inflicting wounds.
Temperament: Aggressive - Although sturdy tankmates may survive alongside this species, it is probably best to keep them in a single species tank.
Same species - conspecifics: Yes - This fish can be kept as a single specimen or in a group of at least 4 or more of its own kind or other Pygocentrus species.

Sex: Sexual differences
This species is not sexually dimorphic. Visual differences between the sexes may possibly be determined if the fish are observed over a long period of time, including pre-spawning activity. However, any color variation is limited to the female being full of roe and the male being in pre-spawning colors. At this time, the male will be more silvery-gold while the female will have more yellow.
Breeding / Reproduction
The Red-bellied Piranha has been bred in home aquariums. Breeding this fish is difficult, however, and no optimal process for doing so has been established. Because this is a very complex species, results can have many variations of spotting, body shape, and coloration.
To attempt breeding, use a very large aquarium that is at least 6 feet in length and 24 inches wide. The first challenge is finding a suitable breeding pair. Sexing is unreliable, although the thickness of the fish has been suggested to indicate gender. A school of at least 6 fish will be needed to have a pair form.
In the wild, spawning usually takes place in the wet season during the months of April and May. Frequent, large water changes should induce breeding as these fish will believe the rainy season has begun. A pair will darken in color, separate from the group, and dig a bowl-shaped spawning pit. The pit will be about 1 1/2 to 2 inches (4 - 5 cm) deep and about 6 inches (15 cm) across.
Do not disturb them during spawning. Spawning takes place with a courtship ritual of swimming in circles and then a ventral-to-ventral interaction. This will induce the female to lay the eggs in the sediment of the pit where they are fertilized. The female will then swim away, and the male will guard the nest. In the wild, the eggs are in clusters and attach to the bottom vegetation.
The eggs should be raised in a separate tank. Each spawn can produce hundreds of fry. Once the fry are free-swimming, they can be fed newly hatched brine shrimp. In nature, they feed on macroscopic plant life. The fry are cannibalistic, so the larger fry will eat smaller siblings. For a general description of characin fish breeding, see Breeding Freshwater Fish: Characins.
Ease of Breeding: Difficult
Red-bellied Piranha are hardy and disease is not usually a problem in a well-maintained aquarium. That said, there is no guarantee that you won't have to deal with health problems or disease. Anything you add to your tank can introduce disease. Not only other fish but plants, substrate, and decorations can harbor bacteria. Take great care and make sure to properly clean or quarantine anything that you add to an established tank so as not to upset the balance. Diseases can be passed along from feeding them live foods, so make sure to quarantine live food before feeding. These fish are also at risk for getting wounds inflicted by tankmates. These can lead to contracting bacterial and other infections.
A good thing about Red Belly Piranha is that due to their resilience, an outbreak of disease can often be limited to just one or a few fishes if dealt with at an early stage. The best way to proactively prevent disease is to give your fish the proper environment and a well-balanced diet. The more closely their environment resembles their natural habitat, the less stress the fish will have, making them healthier and happier. A stressed fish is more likely to acquire disease.
As with most fish, Red Piranhas are prone to skin flukes, parasitic infestations (protozoa, worms, etc.), ichthyobodo infection, parasitic infestations (protozoa, worms, etc.), bacterial infections (general), and bacterial disease. They are additionally prone to wounds from attacks by tankmates, which can then lead to bacterial or fungal infections. Aquarists should read up on common tank diseases. Knowing the signs and catching and treating them early makes a huge difference. For information about freshwater fish diseases and illnesses, see Aquarium Fish Diseases and Treatments.
The Red-bellied Piranha is the most common piranha found for sale in the U.S. However, these fish have provoked fear in conservationists and the media after being irresponsibly released into waterways. Consequently, though they are readily available for sale, they are no longer legal to keep in all states. Before purchasing these fish, be sure to check with the authorities in your area.
Bill Dearman - 2016-05-17 Back in the eighties I was recognised as the first person to breed red bellied piranhas in captivity. The story was covered in Aquarist and Pondkeeper. If anyone would like to make a documentary on these fish and how they breed I have over four hours of crystal clear recordings which I would be willing to sell. Interested? contact email@example.com
blackdome24 - 2016-12-14 hello sirt can i ask how will you know if male or female is your red bellied piranha? and how old or large are they or how to know if you can breed them or how to breed them sir?
Lars Marius Haave - 2016-03-30 Hi I have only 2 red belly's left after they killed the third one. They are beeing very strange : one i half grey half silver and is never calm, he/she is only swimming around and haven't had a break in days. The other one which has bin the most active one is now always calm and never does anything at all. They eat very little and does not Get exited when we feed them. They are also wery jumpy and freaks out when you Get close to the tank. Pleas help me finding a way to save them, i migt gonne have to put them to sleep.
Mike - 2016-05-01 How old are the Piranhas and how large? if one of your fish is swimming around in a circle constantly and the other is nearby you may have a breeding pair, the male will defend a certain nest area, and may even launch an attack towards you if he feels you are a threat to his nest, but unless your fish are of breeding age this is speculative at best. Also you can search to find piranha's spawning online
bassam ronz - 2013-05-16 Hiii every one i have 6 oscars cichlids i albino and 5 tiger with 1 recently baught jack dempsy. Any one knows if i could buy pirhana in this tamk it is 2 meters length and 50 width and 50 higth it is a very big tank
Jeremy Roche - 2013-05-16 I would not recommend this! Pirhana are usually species only fish.
Claude - 2015-11-29 Noooo your tank is a perfect size for a small school of piranhas but the fish you have in it are to large which will lead to problems down the road if your piranha is by its self it will be scared all the time if it is young and die from stress if you get a school of them which that size tank can hold they will team up and slowly kill all of your other fish for protection and if your other fish do survive when the piranhas get larger and need more room they will finish the job from my experience with them the only things I can keep with my piranhas is young guppies and some people have had luck with neon tetras the reason being there to small neons are an expensive experiment is why I haven't bothered I just tank guppies from my other tank when they start over populating the tank and they seem fine when there tiny once they get older though there dead but that's free food vs them killing each others young as would normally happen in a guppie tank when it gets to full
