Comments: Seems to be associated with streams and rivers with clear water, moderate to fast current and a gravel to stony bottom (Ref. 27732).  Found near the bottom in pools of small to medium-sized rivers.  Typically occurs near decaying plant debris where it feeds on insects and other invertebrates.  Possibly moves out into flooded forests during high-water periods.  Apparently found in localized populations and encountered sporadically (Ref. 12693).  Reported as a nocturnal species by villagers in Ban Pakphanang (Laos), where all specimens were obtained at night (Ref. 27732).  Rare in markets (Ref. 12693).
