Brycinus

Brycinus is a genus of ray-finned fish in the family Alestiidae, the African tetras. Like other "African characids", they were formerly included in the Characidae but are actually somewhat more distantly related Characiformes.

Like some other Alestiidae, they are called robber tetras due to their bold and rather carnivorous habits. They are not infrequently kept as aquarium fishes and in their requirements resemble the South American tetras of the Characidae. Unlike these, Brycinus are not well-suited to accompany delicate fishes however and are better kept with dwarf cichlids and similar small but robust companions.
