成熟度: Lm ? range ? - ? cm
Max length : 6.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 9710)
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).
Cross section: compressed.
Adults occur in relatively deep water. They are 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). Adults feed 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)
