Description

Ternetz's pacu is a deep, strongly compressed, disc-shaped characin of the family Serrasalmidae reaching about 23 cm; the group is also called 'silver dollar'. The silvery, round body has a blunt snout with stout cutting teeth. Unlike the related piranhas this is a peaceful plant-eater: it lives on water plants, leaves, fruit and seeds, supplemented with insects, and helps disperse seeds in flooded forest. The species comes from clear, forested rivers and creeks of northern South America, the Guianas and the Amazon region, and swims in schools. Because of its handsome, coin-like shape it is popular in the aquarium hobby.
