背棘 (总数) : 3; 背的软条 (总数) : 29 - 32; 臀棘: 0; 臀鳍软条: 26 - 29. Males are straw-yellow with each scale outlined in black creating a crosshatched appearance, and a red tail with neon submarginal blue band. Females are also crosshatched, but with a slate gray to blue ground color and tail.
雄性对每个鳞片感到麦黄色有黑边创造被以网目线作出阴影的外表,而且红色尾部有氖靠近边缘的蓝色条纹。 雌性也被以网目线作出阴影, 但是有暗蓝灰色到蓝色底色与尾部。

生物学特性     字汇 (例如 epibenthic)

Found mainly around oceanic islands and near reefs along the continental coasts (Ref. 9276). Found in schools in seaward reefs above drop-offs (Ref. 9710). Benthopelagic (Ref. 58302). Feeds on zooplanktons (Ref. 89972).

主要地大洋性岛屿的周围与在礁的附近发现沿着大陆沿岸.(参考文献 9276) 成群出现在海峭壁上面的临海礁石中.(参考文献 9710)

Males establish a territory for spawning and parental care but not for feeding (Ref. 116451). Only females tend the eggs but both parents keep guard (Ref. 116451).西太平洋: 日本南部與琉球,伊豆,馬克斯,維克群島與夏威夷群島。 東太平洋: 美國的南加州與皮特凱恩島,復活島,雷維拉吉哥多島,克利珀頓島, 與加拉巴哥群島.(參考文獻 5227,11482)
