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).
主要生活在半淡咸水。 栖息于在河口附近的浅又混浊的水域的软质底部了。 报告从河口到淡水移动, 但是显然地实际产卵发生于半淡咸水.(参考文献 6868) 此鱼种有一个母鱼蝌蚪鮎运送卵牢牢地黏在身体的下面的特殊模式的卵孵育。 这似乎是促进泥泞的环境的卵的氧化的适应。 繁殖可能发生在每年的较早的部份。 (参考文献 35381)
