Brycinus
 Brycinus is a ray-finned fish genus in the family Alestiidae. 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.
