成鱼是褐色-灰色的背面与腹侧白色的有一些在背部中线附近的微白色的斑块, 与一条宽的褐色斑纹在中线正下方从眼睛后面到尾鳍基底。
Facultative air-breathing (Ref. 126274); Occur in swift-flowing, tea-colored streams coursing through karri forests. Also found in swamps, ponds and roadside ditches. Usually lives in small flowing streams near submerged vegetation. Water inhabited is darkly tannin-stained and acidic (pH 3.0-6.0) (Ref. 44894). Feed on insects and their larvae in water; also on micro-crustaceans. Spawning has been recorded from July to October, peaking between August and September when water temperatures and day length are on the rise. Multiple-spawning females deposit several clutches of eggs over a protracted period of a few weeks in flooded vegetation. Sexual maturity is attained in the first year. Spent adults usually die a few months after spawning (Ref. 44894).
出现在流经 karri 森林的快速流动又茶色的溪流。 也发现于沼泽，池塘与路傍沟渠。 通常生活在水中植物附近的小的流动溪流中。 暗被居住的水是单宁酸-沾染与酸性的 (酸碱度 3.0-6.0).(参考文献 44894) 在水捕食昆虫与他们的幼体; 也在细小的甲壳动物上。 产卵已经被记录从七月到十月, 在八月与九月之间到达高点何时水温与日子长度是在上涨中。 多样的-产卵雌性在茂盛的植物中堆积在数个星期的一长段时间上的卵的一些抓紧。 性成熟在第一个年内被达到。 完成产卵的成鱼通常死产卵的之后数个月。 (參考文獻 44894)
