Comments: Captured specimens were from the swamps or the tidal parts of rivers.  It therefore inhabits the same environment as <i>Trachelyopterus galeatus</i> with which it could establish a mimetic association.  Confusion due to this similarity, as well as difficulty in net-fishing of this fish  (due to its small size, absence of spines) can explain its apparent rarity (Ref. 35381).
