Benthic fish occurring mainly in brackish water. Found on soft bottoms of shallow turbid water near river mouths. The species has a peculiar mode of egg incubation wherein the female banjo catfish carries the eggs firmly attached to the underside of the body. This seems to be an adaptation to facilitate the oxygenation of the eggs in muddy environments. Reproduction takes place in March and June (Ref. 35381).
