Africa: within the drainage basins of the Zambezi, Limpopo, Incomati and Usutu-Pongolo Rivers (Ref. 1440). In the Congo Basin, its distribution is limited to the middle and upper regions (Ref. 26192). Also known from East African rivers and the region of the Cap; south through the Zambezi system (Ref. 7248, 52193) and in the Coroca and Cuanza rivers in Angola (Ref. 11970).
非洲: 在尚比西河，凌波波河， Incomati 與 Usutu 的集水區裡面-澎哥洛河。 在剛果河流域中，它的分布被僅限於中央與上游區域。 (參考文獻 26192) 也已知來自東非河與無邊帽的區域; 南至三比河流域.(參考文獻 7248)

Shoaling species (Ref. 94784). Found in both sediment-free and sediment-rich rocky biotopes; favors clear, running waters in rocky habitats of small and large rivers, also found in lakes and dams over rocky areas (Ref. 5595, 52193). It feeds on diatoms and other small algae from the rocks (Ref. 5595), also on `aufwuchs' from the surface of rocks, tree trunks and other firm surfaces (Ref. 52193). Migrates upstream in masses to breed, using the mouth and broad pectoral fins to climb damp surfaces of barrier rocks and weirs (Ref. 7248, 52193). Some sources give a maximum length of 400 mm standard length (Ref. 2801)
出现于无沉淀物和沉淀物-丰饶的岩石生存环境。 喜欢在岩石的栖息地的清澈又流动的水域小的与大河, 也发现于在岩石区上的湖与水坝。 吃硅藻与其他的小藻类从岩石。 (参考文献 5595) 也吃来自岩石的表面，树干与其他的结实表面的附着生物。 在团中向上游集合繁殖, 使用嘴巴和宽的胸鳍攀登障碍岩石 & 鱼梁的潮湿表面.(参考文献 7248)
