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).
主要出現在半淡鹹水的底棲的魚。 棲息於在河口附近的淺又混濁的水域的軟質底部了。 此魚種有一個母魚蝌蚪鮎運送卵牢牢地黏在身體的下面的特殊模式的卵孵育。 這似乎是促進泥濘的環境的卵的氧化的適應。 繁殖發生於三月與六月.(參考文獻 35381)
