Description

The discus tetra is a characin (Characidae) from northern South America. The species reaches about 9 cm and has a strikingly deep, almost round and strongly compressed, silvery body, to which the name refers. It lives in schools in rivers and streams. As an omnivore it feeds on worms, insects, crustaceans and plant matter. The mirror-like, deep shape helps it vanish into a school from predators. Because of its handsome shape the species is sometimes kept as an aquarium fish; locally it is eaten.
