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).
似乎被伴随着溪流与河川，水质清澈的地方, 和缓到快速的水流与一个砾石到多石底部.(参考文献 27732) 在小型到中型河的水池中发现于靠近底部了。 典型地生活于靠近腐败植物残枝在哪里它吃昆虫与其他的无脊椎动物。 可能地游进被水淹没的森林中在高水位期间时期。 显然地发现于本土化族群而且零星地见到。 (参考文献 12693) 在所有的标本被获得在晚上的 Ban Pakphanang 藉着村民纪录为一个夜行的鱼种了。 (参考文献 27732) 稀有的在市场中.(参考文献 12693)
