Is the rarest of all the endemic freshwater fishes of southwestern Australia. Inhabits coastal streams, lakes, ponds and swamps, where the water is dark and acidic (pH as low as 3.0) and has a large seasonal fluctuation in temperature (11-30°C) (Ref. 27892, 44894). Favors shallow water and is commonly found in association with tall sedge thickets (Ref. 44894). Larva feeds mainly on cladocerans, copepods and dipteran larvae, while juveniles and adults ingest mostly terrestrial fauna (Ref. 6398, 44894). Breeds in the middle of winter in response to flooding. Female lays between 500-1600 eggs each. The majority of adult perishes shortly after spawning at the end of their first year (Ref. 44894). Both male and female attain sexual maturity at the end of their first year of life when they have attained an average TL of 6.0 and 6.3 cm respectively (Ref. 27892). Co-occurs with Edelia vittata over part of its range, but is generally more scarce (Ref. 5259, 44894). Aquarium conditions: pH=7.2, H=8, 24°C water temperature, rock and plant cover, carnivore, peaceful community fish, egg layer (Ref. 6398).
西南方澳洲的所有本地淡水鱼的最稀罕的是。 栖息于海岸的溪流，湖，池塘与沼泽, 在哪里水颜色较深而酸性的 (酸碱度更低到 3.0) 而且在温度 (11-30 °C) 有一个大的季节性的变动.(参考文献 27892,44894) 喜欢浅水区与是普遍发现于邻近高的菅茅丛.(参考文献 44894) 仔鱼主要捕食水蚤, 桡脚类的动物与双翅类昆虫的幼生, 而稚鱼与成鱼摄取大部份陆栖的动物相.(参考文献 6398,44894) 响应洪水泛滥繁殖于冬天的中央。 雌性在 500-1600个卵之间生下每个。 多数的成魚在產卵之後不久在他們的第一的年結束的時候死亡。 (參考文獻 44894) 當他們分別地已經達到 6.0 與 6.3 公分的平均 TL 的時候，雄性和雌性在他們的第一個年結束的時候達到性成熟。 (參考文獻 27892) 以在它的分佈範圍的部份上的 雜斑斷線矮鱸〔Edelia vittata〕 共同生存, 但是是通常較難得的.(參考文獻 5259,44894) 養殖環境條件: 酸鹼度=7.2, H=8 24 °C 水溫，岩石與植物表面，食肉動物, 溫和群居的魚，產卵魚.(參考文獻 6398)
