Anadromous species; ascending both large rivers and streams during floods and spawning in floodwater pools or inundated grasses at margins of rivers (Ref. 105018). Upstream migration at beginning of rains (Ref. 36900) in fairly compact shoals (Ref. 52083). Permanent river populations exist (Ref. 52083). Lake Victoria: in shallow, inshore waters and influent rivers (Ref. 34291). Lake Kyoga: in open waters away from water-lily zone (Ref. 4903). Specialized feeder on epilithic and epiphytic algae (Ref. 12526). Also feeds on rotifers growing on the body of other fishes (Ref. 34291). Caught with weirs and in baskets (Ref. 4967). Oviparous (Ref. 205).
出現於沿岸淺水區水域與流入的河。 (參考文獻 34291) 渡過它生命期的大部份在湖中跨越, 但是在被水淹沒的草地中產卵在永久的旁邊與暫時性的溪流。 用魚樑捕獲了與在籃子中.(參考文獻 4967) 吃碎屑與藻類。 (參考文獻 13624) 也吃生長在其他魚的身體上的輪蟲。 (參考文獻 34291) 卵生的.(參考文獻 205)
