Maturity: Lm 4.3 range ? - ? cm
Max length : 7.4 cm SL 雄鱼/尚未辨别雌雄; (Ref. 44894); 6.7 cm TL (female); common length : 4.0 cm SL 雄鱼/尚未辨别雌雄; (Ref. 5259)
Facultative air-breathing (Ref. 126274); Occurs in shallow streams, drains and temporary pools in generally acidic water around pH 4. Water typically is tea-coloured (Ref. 44894). Feeds mainly on aquatic insect larvae and small crustaceans. Spawn: late winter, early spring; internal fertilization (male with modified anal fin); female laying about 100 eggs. Rapid growth of hatchlings (reaching 2.5 cm by summer). Life cycle may be limited to 12 months. Young fish aestivates in pear-shaped burrow in mud until water returns in autumn. They have no accessory respiratory structures and cannot withstand low oxygen situations (Ref. 36499). About 25-30% of the population attains sexual maturity at the end of the first year. The breeding season coincides with heavy rains between late May and August. The lifespan typically lasts three years, but some fish persist for up to five years (Ref. 44894).
在酸碱度 4 附近的通常酸性水域中出现于浅的溪流，排水沟与暂时的水池。 水典型地是茶-彩色的.(参考文献 44894) 主要吃水生的昆虫幼生与小型甲壳动物。 产卵: 冬季末, 初春; 体内受精;(雄鱼有变异的臀鳍) 母鱼产下大约 100个卵。 人工孵化出之鱼苗的迅速成长.(在夏天之前达到 2.5 公分) 生命周期可能被仅限于 12个月。 幼鱼直到水回返秋天时在泥中的珠状穴中夏眠。 他们没有附属呼吸结构而且不能够抵抗溶氧量低的情形。 (参考文献 36499) 大约 30% 的族群在第一个年底達到性成熟的 25-。 繁殖季節與遲的五月和八月之間的豪雨一致。 壽命典型地持續三年，但是一些魚堅持超過五年。 (參考文獻 44894)
