Oblique groove on side of snout below nostrils, its length about equal to length of naked area enclosing nostrils (Ref 9808).
新鮮的標本有黃色的尾鰭與黑色的肉梗碟; 保存的標本均勻的灰色顏色與深色的鰭.(胸鰭灰白的) 在鼻孔之下的在吻的側邊上的斜的凹槽, 它的長度大約等於被圍住鼻孔 (參考文獻 9808) 的裸露區的長度.
Inhabits coastal to outer reef slopes, usually swimming along upper edges of drop-offs in small schools (Ref. 48637). Descends from the water column to the reef front to be cleaned by Labroides dimidiatus (Ref. 4974). Feeds on benthic algae (Ref. 3145). Forms aggregations, feeding on zooplankton well above the bottom over or in the immediate vicinity of reefs. Males exhibit rapid and striking changes in color pattern during courtship (Ref. 10671).
