Tamaño / Peso / Edad
Madurez: Lm ?  range ? - ? cm
Max length : 23.0 cm TL macho / no sexado; (Ref. 7251); common length : 17.0 cm TL macho / no sexado; (Ref. 3798)
Espinas dorsales (total) : 12; Radios blandos dorsales (total) : 13; Espinas anales: 3; Radios blandos anales: 9 - 10. 6 straight, even, and nearly equally wide bronze-yellow stripes on side (Ref. 26938). Snout short, mouth nearly horizontal and small, the maxilla usually not reaching a vertical at front edge of pupil; fins largely yellow (Ref. 13442).
Body shape (shape guide): fusiform / normal.
Inhabits exposed rocky areas and coral reefs. Often near elkhorn and staghorn corals (Ref. 9710). Commonly found in schools. Juveniles are encountered in Thalassia beds (Ref. 9626). Adults are observed in coral reefs during the day but enters open waters at night to feed on mainly on plankton (Ref. 9626), but also on small crustaceans and mollusks. Marketed fresh (Ref. 3798).
