Inhabits rivers, beels, canals and ponds (Ref. 1479). Prefers soft substrates where it lies concealed in the soft mire of the river bed. It depends upon this concealment for protection and will not even move when it is touched lightly. Lies quietly on the bottom until some prey comes along (Ref. 6868). Apparently a worm-like appendix at the fringe of the mouth is used to attract prey (Ref. 50926). Fairly common in catches, but is not eaten perhaps due to its ugly appearance.
