Benthic fish occurring on sandy-muddy bottoms of brackish waters (Ref. 35381) and coastal rivers (Ref. 36695). 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 probably occurs during the earlier part of the year (Ref. 35381).
出現於半鹹淡水域 (參考文獻 35381) 與沿海的河川沙泥底上的底棲的魚.(參考文獻 36695) 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。 繁殖可能發生在每年的較早的部份。 (參考文獻 35381)
