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). Migrates within rivers. Recorded to move up tributaries in shoals during flood season (Ref. 13337). Feeds on invertebrates, especially midge and mayfly larvae and pupae taken from the bottom and off plant stems. |
