Gregarious. Appears to be active either at night or during the day. Seeks shelter under dead wood and is capable of intestinal breathing (Ref. 35381). Commonly occurs in the lower reaches of large rivers. Known to feed on fruits, thus helping to scatter several plant seeds. Also feeds on small fishes and insects and often manifests the behavior of a detritivore (Ref. 27188). Probably migrate upstream during reproduction. The female lays an average of 50,000 eggs which are fertilized externally (Ref. 35381).
群居的。 似乎活跃的或在晚上或在白天期间。 在枯木下寻找遮蔽而且能够肠内呼吸。 (参考文献 35381) 通常生存于大河的下面范围。 已知吃果实, 如此帮助散布一些植物种子。 也吃小鱼与昆虫而且时常显示吃碎屑者的行为.(参考文献 27188) 可能在繁殖的时候向上游移动。 母鱼生下平均 50,000个卵那是外部地受精.(参考文献 35381)
