Facultative air-breathing in the genus; Occurs in ponds (Ref. 11229) and forest creeks rich in plant debris (Ref. 35381). Benthic fish which feeds on a wide range of food, including organic debris from the bottom. Spawns eggs on sandy substrate, in groups. Unlike the other species of Aspredinidae, the female does not carry her eggs (4,000 to 5,000 per spawning) in bags (cotylophores). It swims with undulating motion of its body and tail, rhythmically ejecting water from its opercles, thus resulting in a forward propulsion (Ref. 35381). Aquarium keeping: needs fine gravel or sand; minimum aquarium size 80 cm (Ref. 51539).
出現於池塘 (參考文獻 11229) ，而且森林小溪豐富的在植物殘枝。 (參考文獻 35381) 吃寬範圍的食物的底棲的魚, 包括來自底部的有機的殘礫。 在砂質底部上產卵卵, 成群。 不像蝌蚪鯰科的另一個種, 母魚不會帶她的卵 (4,000 到 5,000 每產卵) 在袋子 (cotylophores). 它以波動方式游泳它的身體與尾部, 節奏地從它的鰓蓋排水, 如此造成一個向前的推進.(參考文獻 35381) 水族館保持: 需要細砂礫或沙子; 水族館最小體型 80 公分.(參考文獻 51539)
