生物學特性     字彙 (例如 epibenthic)

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).

出現於在沙質與岩石底部上的沿岸淺水區水域, 季節性地出現在泥沙底上面鄰近廣泛的紙草沼澤。 吃小的生物例如介形亞綱動物，水螅與 Diaptomus 。 (參考文獻 9606) 卵生的.(參考文獻 205) 在河上面迴游產卵.(參考文獻 10608)
