Facultative air-breathing in the genus (Ref. 126274); Found in rocky pools at the base of rapids and waterfalls. Occur around submerged vegetation along the edges of pools or slow-flowing water and sometimes in lakes and ponds (Ref. 6896, 33843). Water is usually clear and fresh or darkly tannin-stained and slightly acidic. Tolerate brackish conditions found in many salt-affected rivers of the south-west. A fast swimming species, forming moderately-sized shoals just above the bottom. With the onset of winter rains, these fish move into small tributaries and feeder streams of rivers and wetlands to spawn among flooded vegetation. Sexual maturity is reached the following autumn (Ref. 44894). Feed mainly on insects and small crustaceans. Considered as the most abundant freshwater fish species in southwestern Western Australia (Ref. 6896, 33843, 44894).
在急流与瀑布的基底发现于岩石的水池了。 水中植物的周围出现沿着水池或缓慢流动的水边缘与有时在湖泊与池塘中.(参考文献 6896,33843) 水通常是清澈的与生鲜地或者暗单宁酸-沾染与些微酸性。 容忍被发现于西南方的许多盐-受到影响河的半咸淡的环境。 一个快速的游泳种, 形成一般大小的浅滩在底部正上方。 与冬天的开始雨, 这些鱼移进河的小支流与捕食者溪流中，而且洼地在茂盛的植物之中产卵。 性成熟下一个秋天被达成。 (参考文献 44894) 主要捕食昆虫与小型甲壳动物。 被当作在西南方的西澳大利亞最豐富的淡水魚種了。 (參考文獻 6896,33843,44894)
