Description
Size: 20-25 cm.

Color: Head without yellow bands or streaks; 4 longitudinal yellow lines along flanks below lateral line; belly with a yellow stripe on each side of silvery mid line. A yellow spot below origin of lateral line but no dark saddles on back. Filament of dorsal fin bright yellow, rest of fin rosy, with yellow or orange margin; pelvic fins whitish, with 2nd and 3rd rays more or less pink, bases and axillary scales yellow; anal fin milky white, hyaline or pale blue, with a single yellow stripe; caudal fin rosy, with upper tip and filament yellow.

Suborbital spine are absent. Preopercle with 3 transverse scale rows. Pectoral and pelvic fins are long, reaching to between level of anus and origin of anal fin. First two dorsal spines are close together, almost fused, forming a very long filament. Upper lobe of caudal fin is produced to form a trailing filament. A line drawn up from the posterior edge of suborbital reaching the dorsal profile about 2 to 5 scale rows before origin of dorsal fin. Axillary scale present. Height 3.2-3.3, 4.2 in length with caudal. Head 3.1-3.2, 4-4.1 in length with caudal. Height of head, measured in vertical through hind border of preoperculum, half length of operculum less than length of head. Eye 3-3.4, somewhat more than snout. Inter orbital space somewhat concave, 1.5-1.7 in eye. Mouth oblique, maxillary reaching almost to below front border of pupil. Narrow bands of teeth in the jaws, with a lateral outer row in the upper jaw of about 25 larger teeth, and 4 strong curved canines on each side anteriorly. An outer row of 24 larger teeth of equal size in each ramus of the lower jaw, without canines anteriorly. Suborbital low, its depth half vertical diameter of eye, its posterior angle somewhat obtuse, its hind border forming a more or less straight line, which, when produced, reaches dorsal profile 7-9 scales before origin of dorsal. Preoperculum denticulate behind, depth of the naked limb 1.5-2 in that of the scaly part. Scales beginning on head above posterior half of eye. Dorsal spines flexible, not pungent, the first and second the longest, produced into long filament and longer than length of base of dorsal. Soft part of dorsal higher than spinous part, excepting the filaments, and rounded. First anal spine shorter than second, third longest, equal to horizontal diameter of eye. Soft anal slightly rounded below, pointed behind, less deep than soft dorsal. Pectorals almost as long as head. Ventrals somewhat shorter. Caudal deeply forked, the lobes pointed, the upper lobe produced into a filament. Least height of caudal peduncle 1.8 in its length. Dorsal spines (total): 10-10, Dorsal soft rays (total): 9-9, Anal spines: 3, Anal soft rays: 7.
