背棘 (总数) : 13 - 14; 背的软条 (总数) : 23 - 26; 臀棘: 3; 臀鳍软条: 19 - 22. The abdominal region of females is noticeably thick set. Body is golden yellow; base of the posterior portions of the dorsal and anal fins black; a prominent vertical black bar running across the eye; diagonal rows of black dots on the sides. A filament originating from the soft portions of the dorsal fin rays trails posteriorly (Ref. 4855). Snout length 2.4-2.9 in HL. Body depth 1.6-1.9 in SL (Ref. 90102).
雌性的腹部区域显着地是厚的。 身体是金黄色的; 背鳍与臀鳍黑色的后面的部分的基底; 一条突出的垂直黑色的横带越过眼; 侧边上的斜线列的黑色点。 一个丝状突起在后部地起源于背鳍鳍条尾丝的柔软部位。

生物学特性     字汇 (例如 epibenthic)

Uncommon species (Ref. 9710) found in coral rich areas of clear water lagoon and semi-protected seaward reefs. Usually in pairs or small groups, more wary than most species. Minimum depth reported taken from Ref. 30874. Oviparous (Ref. 205). Minimum depth reported taken from Ref. 128797.

稀有的种 (参考文献 9710) 发现于水质清澈的泻湖与半遮蔽的临海礁石的珊瑚丰富的区域了。 通常成对的或形成小群鱼群, 更小心翼翼的超过大多数鱼种。 最小深度报告取自参考文献 30874 。 卵生的.(参考文献 205)
