Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 3.9 cm SL male/unsexed; (Ref. 97410); 4.7 cm SL (female)
soft rays: 10. Distinguished from other congeners by the following combinations of features: fin shape and rays counts: second dorsal fin rays I/10; anal fin rays I/10; pectoral fin rays 17-19; first dorsal fin with all rays about equal without filaments, and 3-4 rays slightly longer in male; second dorsal fin with higher rays in anterior and posterior rays shorter; squamation: longitudinal scale series 35-38; predorsal region naked, body with median-size ctenoid scales; specific coloration pattern: a dark purple cross band below second dorsal fin base; dorsal half of lateral with irregularly dark brown bars and marks in female; belly greenish blue with three vertical brown stripes in male; second dorsal fin brownish with a diagnostic deep black spot between the first and second branched rays in male (Ref. 76793).
Inhabits fast-flowing streams.

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=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm Total Length, based on all LWR estimates for this body shape (Ref. 93245
Resilience (Ref. 69278
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (11 of 100) .
