Characins, tetras & piranhas

721 species · 27 families

Characins include the tetras, piranhas, and knifefishes: mostly South American and African freshwater fish, often with a small adipose fin. Many have sharp teeth — from the harmless tetra to the notorious piranha with its slicing bite. Small tetras like the neon tetra are among the most popular aquarium fish in the world for their glittering colours. They mostly live in schools in rivers, creeks and flooded forests. It is a hugely species-rich group ranging from tiny to predatory.
