Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 28.0 cm TL male/unsexed; (Ref. 9710); max. reported age: 15 years (Ref. 72479)
(total): 13 - 14;
soft rays: 18. Juveniles black with light blue curve vertical stripes on the sides. Adults are bright yellow on sides and back, dorsal and caudal fins, with numerous blue spots; head and ventral portion of the body, pectoral and pelvic fins dark blue with numerous light blue spots on the posterior portion of the anal fin and the adjacent caudal peduncle area.

Indo-Pacific: Indonesia to Papua New Guinea, north to the Philippines, south to Rowley Shoals and the southern Great Barrier Reef; including Palau and Yap in Micronesia.
