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'. Those that ...
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]
Piranhas are "basically like regular fish with large teeth". [19] A few other species may also occur in large groups, while the remaining are solitary or found in small groups. [3] Although popularly described as highly predatory and primarily feeding on fish, piranha diets vary extensively, [3] leading to their classification as omnivorous. [4]
Piranhas are generally less valued, although they are commonly consumed by subsistence fishers and frequently sold for food in local markets. A few piranha species occasionally appear in the aquarium trade, and, in recent decades, dried specimens have been marketed as tourist souvenirs . [ 6 ]

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.
