Remarks Prefers well-vegetated, muddy bottomed marginal habitats of rivers and floodplains. A shoaling species which moves inshore after dark. Frequency of occurence in Caprivi: occasionally in sandy streams, occasionally on rocky streams, common in standing deep water, common in shallow swamps, and common in shallow flood plains (Ref. 037065).
