Morphology | Morphometrics
Snout profile straight; anterior nostril pierced on front side of a flap; processus dentiformis present; usually no median notch in upper lip, lower lip with a median incision; lateral line complete; anus about 1-2 eye-diameters in front of anal-fin origin; 8.5 branched dorsal-fin rays; 5.5 branched anal-fin rays; caudal fin emarginate, with 8+8 branched rays; axillary pelvic lobe present; body depth 14.9-16.8 %SL; caudal peduncle length 14.5-16.4 %SL, depth 12.7-13.1 %SL, 1.15-1.30 times in length; top of head dotted; body with 10-13 bars, as wide as or slightly wider than interspaces, somewhat wider anteriorly than posteriorly, quite regularly set although some may be incomplete or fused; black bar at caudal-fin base complete, usually with anterior and posterior projections along dorsal and ventral midlines; dorsal fin with two conspicuous black blotches along base, encircling a paler round area; caudal fin bright red in life (Ref. 36949).
Occurs in slow current at the time of collection, but very fast flowing water over smooth basaltic rocks in the rainy season (Ref. 36949).

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=0.00617 (0.00255 - 0.01493), b=3.02 (2.84 - 3.20), in cm Total Length, based on LWR estimates for this Genus-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 3.0 ±0.3 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 (15 of 100) .
