Morphology | Morphometrics
(total): 4 - 6;
soft rays: 19 - 22. This rainbowfish is distinguished by the following set of characters: D IV to VI-I,11-14; A I,19-22; pectoral rays 13 or 14; lateral scales 31-33 (often 33); colour generally brownish on back (blue in life), pale tan or whitish below with blackish (bluish black in life) midlateral stripe from upper edge of preopercle to caudal-fin base, covering about one and a half scale rows for most of its
length and more strongly contrasted in males (Ref. 74958).
Inhabits narrow (to about 15-20 m wide), clear rivers with gradual gradients flowing initially through second growth forest, but entering primary, nearly closed canopy forest after about 1 km upstream from the sea. Collected from deeper pools (to about 2-3 m) over limestone cobble/-gravel bottoms with slow to moderate flow rates; temperature of 25.5° and pH 8.7 (Ref. 74958).
