背棘 (總數) : 7; 背的軟條 (總數) : 29 - 30; 臀棘: 1; 臀鰭軟條: 25 - 27. This species is distinguished by the following characters: D VI, I,30 (I,29-30); A I,26 (I,25-27); pectoral-fin rays 20 (20-21); pelvic-fin rays I,5; segmented caudal-fin rays 17; upper procurrent caudal-fin rays 9 (9-14); lower procurrent caudal-fin rays 12 (11-12); total caudal-fin rays 37-43; gill rakers 6 (5-7) + 17 (17-18) = 23 (22-24). Colouration: elevated part of first dorsal fin blue on anterior edge; median fins are pale yellowish green, caudal fin no markings, outermost edge of second dorsal and anal fin tipped with a yellow or orange spot, one in each interradial membrane space, the spots sometimes coalescing; when alive the body is lavender to lilac; pelvic fins black-tipped; dorsal edge of iris with a black mark at 1 o’clock position, sometimes continuing until interorbital space as a short streak; maxilla black (when alive and preserved); snout bright pink in life (Ref. 128599).
Occurs in relatively deep water. Found over small patches of sand, rubble, or hard open bottoms of steep seaward reefs. Rarely found in less than 40 m and frequently occurs in pairs. Monogamous (Ref. 52884). Feeds on zooplanktons (Ref. 89972). Minimum depth reported taken from Ref. 128797.
出現於相當深的水。 發現在陡峭臨海礁石的沙子，碎石或堅硬開放底部的小區塊上了。 很少發現於少於 40 公尺了與時常成對出現。 一夫一妻的.(參考文獻 52884)
