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]
The piranha may also catch prey by hunting and chasing, where it will lie hidden in the vegetation until its prey swims by. The piranha will then capture its prey. When scavenging, the piranha will eat a wide variety of food, ranging from pieces of debris, insects, snails, fish fins, scales, and plants. [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.
As in the Carnivora however, some largely herbivorous or omnivorous Teleost fishes too, exhibit durophagous behaviour in feeding on plant foods, in that they crack the hard stones of fruit that fall into their water: spectacular examples include relatives of the carnivorous piranhas — such species include Piaractus brachypomus and Piaractus ...

To do this, they need a filtration organ that filters out or traps tiny particles. The exact structure of the organ varies between filter-feeding animals. Filter feeders can also vary greatly in size.
