See Mees (1987: 186) for detailed description. Friel (1994: 86) removed this species from Aspredo to preserve monophyly of that genus.

Occurs mainly in brackish water. Found on soft bottoms of shallow turbid water near river mouths. Reported to migrate from estuary into freshwater, but actual spawning apparently takes place in brackish water (Ref. 6868). 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).
主要生活在半淡鹹水。 棲息於在河口附近的淺又混濁的水域的軟質底部了。 報告從河口到淡水移動, 但是顯然地實際產卵發生於半淡鹹水.(參考文獻 6868) 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)
