Short description

Dorsal spines (total): 14; Dorsal soft rays (total): 17 - 19; Anal spines: 3; Anal soft rays: 18 - 20. Front of body yellow; remaining parts of body, dorsal fin, and front of anal fin black. Caudal fin entirely yellow (Ref. 26938). Front margin of anal fin and edge of gill cover orange; bright blue on upper and lower part of iris. The young of about an inch in length are entirely yellow except for a blue-edged black spot on the upper side of the body posterior to the midpoint; with growth the black spot soon expands to become the large black area covering most of the body and dorsal and anal fins (Ref. 13442).
