細長的身體-卵形的。 幾乎甚至的背鰭與臀鰭輪廓。 當成魚時前額沒有嘴的突起。 肉梗的碟單個, 具有一個半圓的, 逆向地彎曲龍骨脊。 範圍 35 公分 SL。
Generally uncommon species found in steep outer lagoon and seaward reef slopes (Ref. 9710, 48637). Maximum depth reported at 40m (Ref. 37792) Occurs singly or in large schools (Ref. 9710, 48637). Usually seen swimming steadily along upper edges of drop-offs in pursuit of plankton (Ref. 48637). A semi-pelagic fish that feeds on zooplankton, but remains over or near reefs. Also feeds on algae (Ref. 30573). It is cleaned by Labroides and sleeps on reefs at night, taking on a disruptive mottled pattern (Ref. 10671). Caught with nets (Ref. 30573).
不常見的種發現於陡峭的潟湖外部與臨海礁石斜坡.。 (參考文獻 9710,48637) 最大的深度在 40 公尺 (參考文獻 37792) 報告各別地或大群魚群生存.(參考文獻 9710,48637) 通常見到穩定地游泳沿著海峭壁的上緣追逐浮游生物.(參考文獻 48637) 一個半大洋性魚捕食浮游動物, 但是保持礁石上面或附近。 也吃藻類。 (參考文獻 30573) 它是在晚上被 Labroides 清理而且睡在礁石上, 有裂斑的圖案。 (參考文獻 10671) 用網捕獲.。 (參考文獻 30573)
