Characteristic Body moderately deep, fusiform and compressed. A single postmaxillary process; small teeth in jaws, vomer and palatines. Dorsal fin with X spines and 15 (rarely 14 or 16) soft rays; anal fin with III spines and 12 (rarely 13) soft rays; pectoral fin usually with 20 to 22 (most frequently 21) rays. Scales in lateral line 51 to 61 (most frequently 55); upper peduncular scale rows 11 to 13, lower peduncular scale rows usually 15 or 16; scale rows above lateral line to origin of dorsal fin usually 8 to 10 (most frequently 8); scale rows below lateral line to origin of anal fin usually 17 to 20; 4 or 5 scale rows on cheek, predorsal scales usually 21 to 25; dorsal and anal fins scaled, the dorsal with about 2/3 of the greatest height of its spinous part covered with scales; supratemporal band of scales interrupted at dorsal midline by a narrow scaleless zone. Tail fin and peduncle, and body above a diagonal from just anterior to origin of dorsal fin to ventral origin of caudal peduncle bright yellow (except in large ones in western Pacific, yellow does not extend as far as anteriorly); rest of upper 2/3 of body bright blue; lower third silvery white. Indonesian populations have yellow from origin of dorsal and most of the back to below lateral line over the posterior part and tail.
habitats Found primarily around coral reefs, with a preference for coralline lagoons. Feeds on zooplankton in large midwater groups. Forms schools with other caesionids. Migrates to select areas around the reef to spawn near the surface in the entrances of deep ch
