Sometimes, chevron-like bars vestigial, with red dots (sometimes elongated) along the whole body. Anterior dorsolateral portion of flanks light brown, with a golden tint. Flanks above anal fin base greenish blue. Dark melanophores distributed between postorbital region and area above midlength of pectoral fin, forming a broad mid-lateral dark stripe. Dorsum light greenish brown or greenish grey. Small black dots on head, dorsum, flanks and caudal peduncle. Abdominal region whitish. Upper jaw light brown, lower jaw dark gray to brown, lips white. Ventral portion of head whitish with concentration of irregular dark brown spots. Iris orangish yellow to light brown, sometimes with broad black bars on anterior and posterior portions, close to pupil. Dorsal fin yellowish with 3–5 irregular, thin, transverse red bars. Ventral portion of opercle greenish or golden. Anal fin yellow, with darkened distal margin. Base of anal fin light greenish blue, sometimes with narrow red bars. Caudal fin yellow with 4–6 narrow irregular vertical red lines not extending to the ventral portion of fin. In some specimens a small dark grey spot is present at dorsal portion of caudal fin base, especially in smaller individuals. Pectoral fins orange, with distal portion grey. Pelvic fins orangish yellow, with dark margin.
