Description
Dorsal spines (total): 9; Dorsal soft rays (total): 10; Anal spines: 3; Anal soft rays: 8 - 11. Recognized by the thin mid-lateral stripe and elongated blotch at front of dorsal fin between 1st and 3rd spines. Body covered with relatively large scales; large canine teeth in the front of jaws. Max length : 21.0 cm TL. Depth range 25 - 60 m.
Body moderately slender, its depth 2.8 to 3 times in standard length. Head pointed, dorsal profile nearly straight with slight concave inflexion above eye in juveniles and small adults, concave in front of eye in large adults; lower jaw prominent, 2 strong canines situated anteriorly in each jaw; no enlarged tooth present on rear of upper jaw; corner of mouth extends rearward to vertical at forward extent of orbit. Posterior ends of dorsal and anal fins bluntly pointed to rounded; dorsal fin continuous, with IX spines and 10 soft rays, the spines and anterior soft rays of similar length; anal fin with III spines and 8 soft rays; pectoral fins with ii unbranched and 10 branched rays; pelvic fins short, not reaching to anus; caudal fin truncate to double emarginate, with corners produced into short pointed lobes. Scaly sheath extending onto dorsal and anal fins. Lateral line interrupted below posterior portion of dorsal-fin base, with 14 scales on anterior portion and 9 or 10 on peduncular part. Predorsal scales 6, reaching forward to vertical at centre of eye; cheek scales reaching just anterior to forward extent of orbit, broad naked margins adjacent to orbit and free preopercular edge; subopercular scales extending anteriorly to vertical at centre of eye.

Colour
Body light red dorsally, becoming white ventrally with ventral scales flecked with red; a dark midlateral stripe on body; head and dorsal part of body finely flecked with small orange-red and some brown dots, the nape and upper body flecked with tiny white dots; dorsal and anal fins translucent whitish, mottled with light red and marked with irregular whie lines and dots, the dorsal fin with a black spot anteriorly; caudal fin with pinkish white lobes spotted with light red, the central region of fin greenish, shading to yellowish posteriorly, the caudal-fin rays deep blue-green; pectoral fins pale; pelvic fins white with a broad light red band near base.

Biology
Found solitary in caves of steep outer reef drop-offs from 25 to at least 46 m with rich invertebrate growth such as large gorgonians or soft corals. Feeds mainly on fishes, shrimps and other crustaceans. Oviparous, distinct pairing during breeding.
