Coloration: alive: body and head olive dorsally and sides silvery with whitish-gold sheen ventrally; black midlateral stripe bordered with golden yellow; black post-opercular vertical bar present; dorsal fin with dark olive rays and clear membranes; caudal fin colouration similar but with pinkish-orange tinge, particularly on lower half; pectoral, pelvic and anal fins pale brownish-orange tinted distinctly pinkish-orange; iris dark anteriorly and posteriorly, pale yellow ventrally with orange highlight dorsally; specimens from turbid water uniformly pale with faint dark midlateral stripe (Ref. 75045). Preserved specimens: dorsal surface scales densely pigmented with fine melanophores, with a crescent of closely spaced larger melanophores at both anterior and posterior borders of exposed part of scale; pigmentation less intense in centres of lateral line scales and in the row below the lateral line only a few scattered melanophores present on each scale, although anterior crescent is still fairly prominent; in next row below, only a few scattered melanophores present anteriorly and dorsally on each scale; below this, all scales pigment-free except for a few melanophores along the ventral scale row between anal and caudal fins; crescent of dark pigment present behind operculum from lateral line to pectoral fin base; horizontal myoseptum darkly pigmented beneath the scales, forming a fine but fairly intense mid-lateralstripe, most prominent on the caudal peduncle; in many specimens, underlying pigmentation emphasised by additional melanophores along the line on the scales themselves; at base of caudal fin, lateral stripe broadens slightly as a result of heavier scale pigmentation; stripe continues through to posterior margin of caudal fin; mid-dorsal stripe present for full length of body; rays of the dorsal, pectoral and caudal fins lightly pigmented with fine melanophores; pelvics and anal almost pigment free; operculum and snout covered in melanophores, which are more abundant but finer on the snout; both pairs of barbels lightly pigmented (Ref. 75045).
