Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 7.8 cm SL male/unsexed; (Ref. 27732)
Has a flat belly; mouth horse-shoe-shaped, very small (width 4-5 times in head width) and quite distant from the tip of the snout; a single simple ray in pelvic and pectoral fins (Ref. 27732); 10-pelvic fins with 10-11 branched rays; lower lip smooth; anus closer to anal origin than to pelvic base (Ref. 43281).
Inhabits high gradient streams and rivers. Typically found in shallow fast water over bedrock and cobble substrates (Ref. 12693). Occurs in rapid-running mountain streams of the middle Mekong (Ref. 12975). Feed on small benthic animals, primarily insect larvae. Not fished commercially (Ref. 12693).
