Facultative air-breathing in the genus (Ref. 126274); Found in shelter of rocks and boulders in lacustrine habitats, also found in swamps and streams draining in and out of lakes (Ref. 44894). Adults occur in the rocky margin of Clarence Lagoon, its outlet stream and several tributaries that flow into the lake. Adults feed on benthic crustaceans while juveniles feed partly on planktonic crustaceans, and insects and their larvae (Ref. 30189, 44894). Very secretive species, darts for cover under boulders if disturbed. The entire life cycle (may live for up to four years) takes place in fresh water. Adults move into inlet streams to spawn in spring. The demersal eggs take about 2 months to hatch. Fry reside in open surface waters of the lake (Ref. 44894).
发现于在湖泊的栖息地的岩石庇护所与大圆石, 也发现于沼泽，而且排水沟的溪流在湖中来回进出。 (参考文献 44894) 成鱼出现在克拉伦舄湖的岩石的边缘, 它的出口水流与流入湖中的一些支流。 成鱼吃底栖的甲壳动物，而稚鱼吃部分在浮游性甲壳动物 , 与昆虫与他们的幼体上。 (参考文献 30189,44894) 非常躲躲藏藏的种, 为在大圆石下面的表面冲出如果扰乱的。 整个的生命周期 (可能活到向上到四年) 发生于淡水。 成鱼移进中小水湾溪流到产卵于春天中。 沉性卵大约 2个月花孵化。 鱼苗归湖的開放水表面所有。 (參考文獻 44894)
