Épines dorsales (Total) : 14; Rayons mous dorsaux (Total) : 19 - 21; Épines anales: 3; Rayons mous anaux: 20 - 21. Tail and pectoral fins entirely yellow. Black spot on forehead has electric blue spots and is surrounded by narrow, electric blue ring. Large blue spot at base of pectoral fin (Ref. 26938). Adults develop short spines on the margin. The color of large adults is purplish blue with yellow-orange rims to the scales; head above eye dark blue, below greenish yellow; mouth, chin, throat, chest and abdomen purplish blue (Ref. 13442)
Body shape (shape guide): short and / or deep; Cross section: compressed.
Found on coral reefs. Generally occurs solitarily or in pairs. Moves gracefully between seafans, seawhips, and corals (Ref. 9710). Stomach contents of 26 specimens indicate that the species feeds almost exclusively on sponges supplemented by small amounts of algae, tunicates, hydroids and bryozoans. Young pick ectoparasites from other fishes (Ref. 9710). Marketed fresh (Ref. 3797).
