Africa: Zambezi, Okavango, Pungwe, Limpopo, and Buzi River systems southwards to the Pongolo River; absent in Kafue and Cunene Rivers (Ref. 7248, 52193).

Diagnosis: With striking vertical bars, lateral line curving down towards the ventral surface of the body and a large curved mouth (Ref. 13337).The dorsal fin is rounded; barbels absent (Ref. 13337).
Body shape (shape guide): elongated.
Prefers clear, flowing waters of larger perennial rivers, frequenting pools below rocky rapids (Ref. 2801). Found also in quiet water with aquatic wed cover. Lives in shoals, usually in shallow water over sandy bottoms. It feeds on aquatic larvae and insects, shrimps and small crustaceans, from surface or water column (Ref. 13337, 52193). Breeds in spring and summer (Ref. 7248, 52193). Also caught with dip nets (Ref. 4967).
