; 淡水 底中水層性; 河川洄游 (Ref. 51243). 熱帶; 11°S - 27°S
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.

Max length : 47.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 52193); 最大體重: 6.0 kg (Ref. 52193)

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).
偏愛終年不斷之河川的流動水域。 罕見在水壩中。 吃各式各樣的食物, 主要地藻類與水生的昆蟲幼生; 也吃小魚, 蝸牛, 淡水貽貝而且漂流生物例如甲蟲與螞蟻。 繁殖於春天與夏天, 在雨水傾注的河中向上游移動產卵於急流中。 雄性在 70 公分 FL 時成熟,雌性在 28 公分 FL 時成熟。 在許多南非德蘭士瓦河中與小規模 yellowfish 生存在一起。 (參考文獻 7248)
