More on author: Peters.
Environment: milieu / climate zone / depth range / distribution range
Freshwater; benthopelagic; potamodromous (Ref. 51243); depth range 30 - 30 m. Tropical; 24°C - 28°C (Ref. 2059); 10°N - 28°S
Africa: within the drainage basins of the Zambezi, Limpopo, Incomati and Usutu-Pongolo Rivers. 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) and in the Coroca and Cuanza rivers in Angola (Ref. 11970).
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 25.0 cm SL male/unsexed; (Ref. 94784); max. published weight: 900.00 g (Ref. 7248)
Vertebrae: 29 - 31. Lips plicate; dorsal fin concave with 9 to 10 branched rays; eyes in superolateral position; genital orifice very far from origin of anal fin; body cylindrical, slightly elongated; snout truncate with deep transverse furrow and fleshy appendix directed upwards (Ref. 26192). Dark lateral band present in young fish only.
Shoaling species (Ref. 94784). Occurs 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; feeds on diatoms and other small algae from the rocks (Ref. 5595). Also feeds on `aufwuchs' from the surface of rocks, tree trunks and other firm surfaces; migrates upstream in masses to breed, using the mouth & broad pectorals to climb damp surfaces of barrier rocks & weirs (Ref. 7248). Ref. 2801 gives a max. length of 400mm SL.
