Morphology | Morphometrics
soft rays: 8. With unique color pattern consisting of a yellowish background with a black stripe along dorsal mid-line and one from tip of snout to caudal fin base through eye and along lateral line; 1 (-3) small vertically elongated spots over lateral stripe; in life, the spots are surrounded by a whitish area (Ref. 39226).
Inhabits streams with moderate to strong current over sandy or pebble substrate. Feeds on may-flies. Observed to form small troops of up to 20 individuals above the substrate around large rocks. This is in contrast with most of the nemacheilines which live solitary under stones. A female measuring 4.16 cm SL with distended belly and ripe ovulae, about 0.7 mm in diameter (Ref. 39226).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00661 (0.00308 - 0.01417), b=3.01 (2.83 - 3.19), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 2.8 ±0.3 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (13 of 100) .
