Facultative air-breathing in the genus (Ref. 126274); Lives in rocky lake margins and occurs to a lesser extent around submerged vegetation and log snags. Usually around rocks and boulders on lake margins in darkly tannin-stained water. Juveniles shoal in open water near lake margins. Spring spawning occurs in small feeder streams. Eggs are deposited in sheltered positions among vegetation, rocks or woody debris and take about 3-4 weeks to hatch. Sexual maturity is reached after the second year but most fish breed in their third or fourth year (Ref. 44894). Feeds on crustaceans and insect larvae. Spawning probably occurs in spring as juveniles are numerous during summer months.
生活在湖边岩石而且水中植物与圆木断枝的周围对较少的范围出现。 通常在暗单宁酸沾染的水湖边缘上的岩石与大圆石的周围。 稚鱼浅滩在开放的水域中在湖边缘的附近。 在小的捕食者溪流产卵的春天。 卵被沈积在植物, 岩石或者植物残砾之中的掩蔽位置而且大约 3-4个星期花孵化。 性成熟被达成在第二年之后但是在他们的第三或第四的年内大多数的鱼繁殖.(参考文献 44894) 吃甲壳动物与昆虫幼生。 可能在春天产卵稚鱼时是很多的在夏天数个月期间。
In captivity, eggs are deposited under flat rocks as well as underneath aquatic vegetation and submerged driftwood.大洋洲: 在南方的塔斯梅尼亞，澳洲中已知只來自湖小販與湖戈登了。
