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).
