|Common name||Red-Bellied Piranha, Red Piranha, Natterer's Piranha
|Scientific name||Pygocentrus nattereri|
|Synonyms||Serrasalmus nattereri (not valid)|
|Origin||Large areas of the Amazon and its major tributaries.|
|Tank setup||A large tank with bogwood, and a few robust or plastic plants for decor.
A shoal of adults will require a tank of 100 gallons plus. Heavy-duty filtration is essential.|
|Compatibility||A highly predatory carnivore, keep in a shoal in a species tank.|
|Water chemistry||Fairly soft, acidic water (pH 5.8-6.8) prefered, but not essential.|
|Feeding||Carnivore: Live or dead meaty foods. There is no particular need to feed live fish, as they can easily be weaned onto
thawed mussel, prawn, etc - some even take pellets which can help to provide a varied diet. The use of "feeder fish" carries a strong risk
of introducing disease.|
|Sexing||No clear sexual differences. Breeding females may appear more robust in shape.|
|Breeding||Eggs are laid among plants or in a pit in the substrate and defended by the parents.
Hatching takes around 2-3 days.|
|Comments||This fish is infamous as a highly dangerous carnivore. Although its reputation is somewhat exaggerated, it
is wise to take precautions when carrying out tank maintenance. The fish may actually appear rather timid if kept
in a brightly lit aquarium with little cover.|
This species may be confused with P. cariba, which occurs in the Orinoco river, rather than the Amazon.
