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魚的最稀罕的是。 棲息於海岸的溪流,湖,池塘與沼澤, 在哪裡水顏色較深而酸性的 (酸鹼度更低到 3.0) 而且在溫度 (11-30 °C) 有一個大的季節性的變動. 仔魚主要捕食水蚤, 橈腳類的動物與雙翅類昆蟲的幼生, 而稚魚與成魚攝取大部份陸棲的動物相。 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) 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)
