Description

The tigerfish is a streamlined, silvery predator of the family Alestidae (African tetras) reaching about 78 cm. Thin, dark lengthwise stripes run along the silver flank; the fins are often reddish and the jaws bear large, dagger-like teeth that protrude when the mouth is closed. The species comes from large rivers and lakes across much of Africa, including the Nile, Niger, Senegal and the Congo basin. It is a fast, fierce piscivore that hunts other fish in groups or from ambush. Because of its power and aggression it is one of the most prized sport fish of Africa. The sharp teeth can bite dangerously when unhooking.
