Overview

Found in schools, usually close to the surface, of rivers.
Widespread South America

Popular Aquarium fish.
Related to Piranha's but these are strictly vegetarian!
Piranha's have a fearsome reputation (because of James bond 007) as a voracious predator that can strip flesh off bones in minutes, although they have razor sharp teeth they are in fact quite timid scavengers.
