Facultative air-breathing in the genus (Ref. 126274); Adults inhabit rivers, creeks and billabongs, usually in quiet or slow-flowing water among vegetation, around log debris or beneath undercut banks. Feed on insects, fishes and crustaceans. Spawn between October and February. The male guards the nest, which is located on a solid surface, frequently on the ceiling of a rock crevice or on a submerged log. Each nest contains up to 70, 000 eggs. The incubation period lasts between 5-7 days (Ref. 44894).
成魚棲息於河,小溪與死水潭,通常在植物之中的安靜或緩慢流動的水, 廢棄圓木的周圍或在堤岸下之下。 捕食昆蟲,魚與甲殼動物。 在十月與二月之間產卵。 雄魚保衛巢,是位於一個堅硬的表面上, 時常在岩石裂隙的頂蓬上或在一個水下的圓木上。 每個巢包含向上到 70, 000個卵。 孵卵期在 5-7 數天之間持續。 (參考文獻 44894)
