In Lake Kyoga in or near water lily swamps (Ref. 49805). In Lake Victoria in shallow inshore waters over both sandy and rocky bottoms, and seasonally over muddy bottoms adjacent to extensive papyrus swamps (Ref. 9606). Predominantly insectivorous, feeding mainly on chironomid larvae (Ref. 12526), but also feeds on small organisms like Ostracoda, Hydracarina (Ref. 9606, 12526), Conchostraca (Ref. 12526) and Diaptomus (Ref. 9606). Crustaceans, gastropods, fish eggs and detritus are also taken (Ref. 9606). Males grow to larger size than females; breeds twice a year during rainy seasons; migrates up the river to spawn (Ref. 10608). Oviparous (Ref. 205).
出现于在沙质与岩石底部上的沿岸浅水区水域, 季节性地出现在泥沙底上面邻近广泛的纸草沼泽。 吃小的生物例如介形亚纲动物，水螅与 Diaptomus 。 (参考文献 9606) 卵生的.(参考文献 205) 在河上面回游产卵.(参考文献 10608)
