Live feedings to captive piranhas can introduce diseases [citation needed], and goldfish contain a growth-inhibiting hormone, which in turn will affect piranhas [citation needed]. Red-bellied piranhas, particularly when juvenile, will sometimes bite one another in the aquarium , normally on the fins, in behavior called 'fin nipping'.
Piranhas will often scavenge, [9] and some species such as Serrasalmus elongatus are specialized scale-eaters, feeding primarily on scales and fins of other fish. [3] Scale- and fin-eating is more widespread among juvenile and sub-adult piranhas. [20] Piranhas lay their eggs in pits dug during the breeding season and swim around to protect them.
This characteristic combined with its large size make it a danger to humans. Piranha's attacks on humans are anecdotal for the most part. The piranha mostly prefers to eat small fish and insects, along with seeds and aquatic plant material. The pygocentrus piraya plays a key role in their ecosystem by regulating the population of other fish [5]

Pygocentrus cariba or black spot piranha is a species of piranha endemic to Venezuela and Colombia; specifically, to the Orinoco River basin lowlands and the Llanos region. This species can reach a total length of 27.9 centimetres (11.0 in). It is popular as a game fish. [2]
Like most fish, when the wimple piranha feeds on small fish or scales floating in the water, it uses suction feeding. However, to feed on scales attached to fish, it uses ram feeding, where the predator will charge at the fish; the force of this collision actually knocks scales free. The teeth are used to scrape scales from the body.
The black piranha was first formally described in 1766 as Salmo rhombeus with the type locality given as Brokopondo on the Suriname River in Surinam. [6] When Bernard Germain de Lacépède created the genus Serrasalmus in 1803 the only species he placed in it was Salmo rhombeus , so this species is the type species of its genus. [ 7 ]
