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。 似乎活躍的或在晚上或在白天期間。 在枯木下尋找遮蔽而且能夠腸內呼吸。 (參考文獻 35381) 通常生存於大河的下面範圍。 已知吃果實, 如此幫助散佈一些植物種子。 也吃小魚與昆蟲而且時常顯示吃碎屑者的行為.(參考文獻 27188) 可能在繁殖的時候向上游移動。 母魚生下平均 50,000個卵那是外部地受精.(參考文獻 35381)

Generation time: 2.3 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
回復力 (Ref.
