Épines dorsales (Total) : 8; Rayons mous dorsaux (Total) : 9; Épines anales: 2; Rayons mous anaux: 8. A small to near pupil-sized (Ref. 48635) basicaudal spot is centered at the level of the lateral stripe (Ref. 37816). Its lower edge at level with the lower ray of the central two rays in the caudal fin. The spot is usually absent in deep water or at night and often fades in the afternoon (Ref. 48635).
Found in relatively clear waters on reef flats and lagoon and seaward reefs to a depth of at least 25 m. Cryptic under ledges by day, singly or in small groups (Ref. 1602, 48635). Feeds on small invertebrates (Ref. 89972). Minimum depth range reported taken from Ref. 11890. Frequent at base of coral heads or under ledges (Ref 90102).
