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).
