Morphology | Morphometrics
spines: 0. Differs from its congeners in Indochina by the combination of the following characters: body with 8-13 quite regular dark bars usually meeting their homologues on back; bars not very contrasted and usually faint on lower half of body; bars on caudal peduncle not reaching ventral midline; bars on predorsal part of body not extending downward beyond lateral stripe in specimens larger than 40 mm SL; prominent lateral stripe often darker than bars; lateral line complete; pelvic fin origin below branched dorsal-fin rays 1-2; caudal fin with 9+8 branched rays; pelvic fin with 8 rays; a complete black bar at caudal-fin base; eye diameter 9.1-21.3% HL, located dorsally and interorbital width 15.0-34.8% HL; caudal peduncle 1.3-1.6 times longer than deep, its depth 10.2-12.6% SL; lateral head length 22.0-25.2% SL; short crests on caudal peduncle; caudal fin deep and emarginate; median caudal-fin ray 63.7-77.6% of length of upper caudal-fin lobe (Ref. 40772).

Estimates of some properties based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00102 (0.00046 - 0.00225), b=3.06 (2.88 - 3.24), based on all LWR estimates for this body shape (Ref. 93245
Trophic Level (Ref. 69278
): 3.1 ±0.4 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (14 of 100) .
