Facultative air-breathing in the genus (Ref. 126274); Live in the margins of lakes and streams, usually in rocky areas or around vegetation and debris. Bottom-dweller in shallows of lakes and inlet streams over rocky substrates. Often sheltering in crevices under rocks, woody debris or among aquatic plants. May also occur in deeper lacustrine waters. A nocturnally active, seldom seen species. Breed in summer (December-January), releasing demersal eggs among rocks at lake margins which hatch in two weeks. Juveniles swim in midwater feeding on plankton, and colonise the bottom after about six months. Sexual maturity is attained at the end of the first year; the maximum life span is probably about three years (Ref. 44894). Feed on insects, small crustaceans, algae and eggs of other galaxiids.
生活在湖泊与溪流的边缘, 通常在岩石区或植物与残砾的周围。 在湖与小水湾的浅滩中的底栖鱼类在岩石的底部之上的溪流。 时常在岩石下面的裂隙隐匿, 植物残砾或在水生植物之中。 可能也更深地出现在湖泊的水域。 夜行活跃,少见的种。 繁殖于夏天 (十二月-一月),在二个星期内孵化的湖边缘释放在岩石之中的沉性卵。 稚鱼游泳在浮游生物上在中层水域觅食, 而且在开拓殖民地底部大约六个月之后。 性成熟在第一个年结束的时候被达到; 三年的大约被可能是的最大寿命.(参考文献 44894) 吃其他南乳鱼科鱼类的昆蟲，小型甲殼動物，藻類與卵。
