Body shape (shape guide): elongated; Cross section: compressed.
Collected in swift creeks under forest cover (Ref. 36949). Also recorded from a stream with clear water ((16 °C; pH 8.1; 250 μs/cm; measured on 1 January 2011 at 11:00 am) that flowed over boulders and rocks with moderate to fast current. Found syntopic with nemacheilids Schistura macrocephalus and Pteronemacheilus meridionalis, the snakehead Channa gachua, and cyprinids such as Barilius pulchellus, Devario chrysotaeniatus, Poropuntius huangchuchieni, and Scaphiodonichthys acanthopterus (Ref. 95066).
