Tip of dorsal fin black, with yellow band below; pectoral axil yellowish, with dark dots, sometimes appearing black (covered by fin). Back with about 10 broken, black, vertical bands (formed of patches) from behind head to end of soft dorsal, laterally extending to a little below lateral line. Abdomen with black pigment spots. Snout margin grey. A black curved band from lower margin of eye to posterior angle of lower jaw. Spinous dorsal membrane between 2 to 6 spines black at the upper one-third portion. Soft dorsal, pectorals, ventrals and anal colourless. Caudal dusky along posterior margins of lobes. Innerside of pectoral base dotted black from where a line of black pigment spots runs down along edge of lower half of gill opening covered by the opercular flap. A line of black pigmet spots runs from the upper angle of pectoral base to opposite end of soft dorsal along the median line of the side of the body.

Body elongated, compressed and oval. The dorsal profile showing a concavity on top of head and is less convex than ventral profile. Its depth is nearly 1/3rd of standard length. Naked head, with nuchal spine. Mouth strongly oblique, nostrils situated above eyes. Protracted mouth pointing upward, Tip of maxilla reaching well below level of lower margin of eye. Body depth twice or slightly more than standard length. Lateral line ending before dorsal fin. Dorsal spines (total): 8 - 8, Dorsal soft rays (total): 16 - 16, Anal spines: 3, Anal soft rays: 14. Snout pointed. Interorbital space concave, the two ridges bounding it continuing as the outer edges of nuchal spine, the median portion of which is not raised above their level and is about 2 in head. One small spine on head, immediately above the eye and opposite its front border, opposite which the ridge bounding the interorbital spaed commences. Mouth when protracted forms a tube directed upwards, gape of mouth opposite about middle of eye and the tip of maxilla far in front of the front border of eye. Mouth small, lips broad and thin, lower lip broader and smaller than the upper which is like a loop over the lower. Lower margin of lower jaw slightly concave, at right angles to mouth slit. Preopercle with an obtuse angle, its lower margin finely serrate. Teeth minute, numerous, in a villiform band; gill rakers long and pointed, each with about 34 small, sharp spines on either side. Scales small, all over the body including the breast. Lateral line shows a slight concavity at first, later running slightly less convex to dorsal profile, extending posteriorly almost to base of caudal. Dorsal and anal spines weak, compressed. Second to fifth dorsal spines and the third anal spine showing sculpture along the posterior margin almost for the entire length. Ventrals with axillary scales, their tips not reaching the origin of anal. Caudal deeply forked.

Breeds in rainy season.
