Dorsal soft rays (total): 10-10; Anal soft rays: 9-9; Vertebrae: 39-40. Coreoleuciscus aeruginos differs from C. splendidus by the following body coloration and shape and/or presence of black bands on dorsal, anal and caudal fin rays: bluish-green line above the luteous line (vs. golden line immediately above a luteous line that runs along a lateral line on side of body); a luteous line immediately above a black line present during the spawning season (vs. bright yellow line immediately above a violet and bluish line running along lateral line on side body during spawning season); dorsal fin with a thin and continuous band both distally and basally (vs. a thick and discontinuous distal band and a thick and continuous basal band); anal fin with thin and relatively short distal band and without basal band (vs. anal fin with quite thick and long distal dark band and short basal band); and caudal fin with with three stripes in centrosymmetric structure, a thick and continuously band distally across lobes, one pair of two thick bands separated into two lobes medially, and a thick and short one at the basal part (vs. seven bands in centrosymmetric structure, three pairs of six thin bands separated into two lobes at medial and distal-most areas and a thin basal band extending outwards (Ref. 100736).
