Max length : 8.0 cm SL male/unsexed; (Ref. 27732)
A conspicuous distal blotch on the dorsal fin; a few scales on the sides with faint black crescent-shaped marks on their base; barbels absent or rudimentary (Ref. 27732); body relatively deep, depth 2.5-2.7 times in SL (Ref. 43281).
Found at bottom depths over gravel in areas with fairly strong currents. Occurs in the main stream of the middle Mekong with populations in fast flowing forest streams (Ref. 12693). Enters flooded fields (Ref. 12975). Feeds on worms, insect larvae, and crustaceans living in bottom sediments, along with algae (Ref. 12693).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5039 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01175 (0.00548 - 0.02519), b=3.00 (2.82 - 3.18), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 2.9 ±0.33 se; based on food items.
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (12 of 100) .
