Africa: widespread from the middle and lower Zambezi south to the Phongolo system (Ref. 7248, 52193). Also known from the Luachimo River, middle Congo River basin, in Angola (Ref. 11970, 120641). Reported as Labeobarbus cf. marequensis from the lower Congo (Ref. 94750); needs confirmation.

Prefers flowing waters of perennial rivers; uncommon in dams (Ref. 52193). It feeds on a wide variety of food items, primarily algae and aquatic insect larvae; also small fishes, snails, freshwater mussels and drifting organisms such as beetles and ants (Ref. 52193). Breeds in spring and summer, migrating upstream in rain swollen rivers to spawn in rapids; males mature at 70 mm FL, females mature at 280 mm FL (Ref. 52193). Occurs with the bushveld smallscale yellowfish, Labeobarbus polylepis in southern Limpopo tributaries (Ref. 7248, 52193).
