Main Ref. Gosse, J.-P., 1984
Remarks Nocturnal shoaling species; favors large river channels with a soft bottom and fringing vegetation (Ref. 7248). Found mainly in sheltered bays, lagoons and swampy areas. Occurs also in typical sandy/rocky rivers (Ref. 13337). Frequency of occurence in Caprivi: frequently on rocky streams, occasionally in standing deep water (Ref. 037065). Feeds on insect larvae at night. Known to migrate up tributary rivers of Lake Kariba during rainy season,though it is not yet clear whether this is a breeding migration (Ref. 13337). Breeds during the rainy season; females carry up to 5,000 eggs.
