Hydrocynus brevis, also known as the tigerfish, Nile tigerfish or Sahelian tigerfish, is a predatory freshwater fish distributed throughout northern Africa.

Hydrocynus brevis is silver in colour when young, with thin black horizontal stripes and an elongated body that tapers at both ends. As the fish grows, it will develop a bronze coloration and the stripes will fade. The ventral and caudal fins have a slight red-orange tint, and the adipose fin is grey to black. It grows to a length of 86 centimetres (34 in) SL.[3]

Distribution

Hydrocynus brevis has a wide distribution. It is found from Senegal to Ethiopia, throughout the Nile. In Northeast Africa it is found in the Ghazal and Jebel systems, Sudan, as well as Baro River, Ethiopia. In Western Africa it is known from Chad, Niger/Bénoué, Volta, Senegal and Gambia.
