| Remarks | 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. Frequency of occurence in Caprivi: occasionally in sandy streams, abundant on rocky streams (Ref. 037065). 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. Masses upstream in masses to breed, using the mouth & broad pectorals to climb damp surfaces of barrier rocks & weirs (Ref. 7248). |
