Color: In preserved specimens darker or lighter brown, fins generally of a darker color. Caudal sometimes yellow and distal half of dorsal and anal sometimes dusky or whitish. Anal sometimes with one or two whitish longitudinal bands in young. A dark spot at origin of lateral line, another on superior part of base of pectoral, and third on upper part of caudal peduncle, immediately behind dorsal. The last spot often with a white anterior border in young. One, two, or all three spots may be absent. In young specimens there are generally white or bluish lines, running from snout above, through and below eye. The upper ones continued as rows of spots along back and often reaching a dark, white edged ocellus on the dorsal. This ocellus is sometimes situated in the anterior, sometimes in the posterior part of the soft dorsal. It generally disappears, but sometimes remains visible as a distinct or faint dark spot. White or bluish spots may also be present in young on all the scales of the body and tail, and of the scales of the dorsal and anal sheaths. In semi adults traces of bands on the head and of the spots on body and tail, especially on caudal peduncle, may still be visible. In very young specimens the ventral spine may also be white or bluish. A dull greenish black species with a small black saddle-spot on the caudal peduncle, edged with blue. Juveniles with a blue-edged ocelli near the end of the dorsal fin.

Height 2-2.2, 2.5-2.8 in length with caudal. Head 3-3.2, 4-4.5 in length with caudal. Length of head 1.1-1.2 in its height. Eye 3.3-4.3, 0.8-1.1 in snout and 1.1-1.4 in convex inter orbital space. Mouth oblique. Maxillary reaching to below front border of eye in young, in adults somewhat beyond vertical through nostril. Preorbital and suborbital naked, the preorbital with 3-6 spines, directed backwards, the suborbital much narrower and with shorter denticulations. In young ones the preorbital has one flat spine only and the serrations on the suborbital are less distinct. Three transverse rows of scales on preopercle, sometimes only two rows near narrow posterior limb, which is naked. Inferior limb scaly. Hind border of preopercle coarsely serrated. Scales on upper part of head reaching to between nostrils. Dorsal spine increasing in length to the fourth, following spine sub equal or the posterior ones slightly longer. Last spine about equal to post orbital part of head. Soft dorsal rather pointed, the 8th or 9th rays longest and equal to head without snout. First anal spine equal to or a little less than half length of second, which is as long as but stronger than last dorsal spine. Soft anal somewhat more rounded than soft dorsal, its longest rays as long as those of dorsal. Pectorals half length of snout shorter than head. Ventrals with the first ray produced, somewhat longer than head. Caudal forked, the lobes slightly pointed in young, rounded in adults. Dorsal spines (total): 13; Dorsal soft rays (total): 14 - 15; Anal spines: 2; Anal soft rays: 14 - 15.
