Comments: Abundant in streams and rivers with gravel or rocky substrate and high water velocities (Ref. 40772).  Resistant to organic pollution and can survive in streams that flow through villages and towns and exhibit strong signs of human perturbation (Ref. 40772).  Most abundant in riffles and rapids with current velocities more than 1 m/s below the surface (Ref. 40772).  Found in small high gradient rivers and small mountain streams, as well (Ref. 40772).  Often associated with <i>Poropuntius</i> sp., <i>Annamia normani</i>, <i>Schistura dalatensis</i> and <i>Glyptothorax laosensis</i> (Ref. 40772).
