Maturity: Lm ?  range ? - ? cm
Max length : 5.0 cm SL male/unsexed; (Ref. 30857)
(total): 7 - 8;
soft rays: 6 - 9. Depressed head and body; generally pale coloration with 6-7 faint vertical bars and black dots on cheeks. Sexually dimorphic: males with more depressed head and body, a larger mouth, and darker fins. Male with about 40 rounded blackish brown spots on cheeks, usually larger than half of pupil; body with 7 lateral blackish brown bars and several rows of black or brown spots; second dorsal with usually 1 simple and 8 branched rays; anal fin with usually 1 simple and 7 branched rays (Ref. 43281).
Collected both in small streams and larger rivers, among stones and boulders, with moderate to swift current (Ref. 33279). Feeds on zooplankton and insect larvae. Occasionally marketed fresh in mixed catches (Ref. 12693).

Bayesian length-weight: a=0.01023 (0.00444 - 0.02358), b=3.05 (2.86 - 3.24), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.3 ±0.43 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) .
