Colour

Fresh fish shortly after death with head and body below eye and mid-line pale red and a red belly margin that extends distally to caudal-peduncle and caudal-fin ventral margins; head dorsally from eye level, and body above the eye to the dorsal margin and base of the fins, with a red stripe ending behind the second dorsal fin and overlain in its middle part by a pink stripe from behind opercle to end of second dorsal-fin base; the stripe increasing in width from about half pupil size to orbit diameter posteriorly; mid-body below lateral line to level of pectoral-fin base pale orange to yellowish, connected anteriorly to a pale-yellowish stripe of about pupil to orbit diameter that descends below eye to posterior maxilla; scales on body with red or pale-red margins, forming a row of dark-red spots along dorsal body margin from behind first dorsal fin to behind second dorsal fin; scales on caudal peduncle with pink dots; pupil black, iris red and white; barbels white suffused with pale-reddish along proximal two thirds and pale-yellowish towards tip; first dorsal fin with mostly pale-red spines and partly red, partly hyaline interspaces; second dorsal fin basally red and distally yellow, longitudinally traversed by white-bluish lining along distal third of fin; caudal fin red at base and lower fin lobe with red ventral margin; upper caudal-fin lobe dorsal margin proximally pale red, then pale orange and yellowish towards fin tip; inner part of caudal-fin lobes pale yellow with yellow fin rays; pectoral fins pale-red with some red patches close to base; pelvic fins pale-red with red spine and rays; anal fin pale red at base, the distal two-thirds of fin longitudinally traversed by alternating yellowish and bluish-white lining; preserved fish pale brown or brown.
