Possible Tank Mates: Because of their aggressive nature this species is better kept alone. A large pleco or snails may work out, but no guarantees. This species should not be kept in groups in captivity due to their aggressive nature.

Filtration and Setup: Heavy filtration is highly recommended, The tank should be decorated with large rocks as well as floating plants and bog wood is appreciated. Lots of open swimming space and dim lighting is recommended.
Coloration: The Black Piranha has a powerful body and large, razor-sharp triangular teeth. Juveniles are a more light color than adults, who's bodies and fins are a blackish gray. Males are more golden, with red in the belly, while females are more yellow. Once mature bot males and females will have a red eye.
Breeding: In the wild Black Piranhas are substrate spawner's that build a nest among the vegetation and bottom detritus and deposit the eggs there. This species will get downright mean during this process and do just about anything to guard their nest. Any serious attempt of breeding Black Piranha should be done in a tank no less than 200 gallons in capacity. Sexing this species is unknown.
