A tropical, demersal species confined to freshwater environment unlike other congeners (Ref. 33568). Collected from below surface in channel with sandy-slime bottom (pH 8.0, conductivity 478 µÊS/cm, dissolved solids 242 mg/l, dissolved oxygen 6.9 mg/l, and 26°C) using a 90 cm seine net. Food fish (Ref. 93806).
