Environnement : milieu / zone climatique / profondeur / gamme de distribution
Écologie
marin récifal; profondeur 0 - 40 m (Ref. 9710), usually 3 - 30 m (Ref. 27115). Tropical; 23°C - 26°C (Ref. 27115); 34°N - 7°N, 99°W - 58°W

Taille / Poids / Âge
Maturité: Lm ?  range ? - ? cm
Max length : 25.0 cm TL mâle / non sexé; (Ref. 26340); âge max. reporté: 3.00 années (Ref. 3420)
Épines dorsales (Total) : 8; Rayons mous dorsaux (Total) : 12 - 13; Épines anales: 3; Rayons mous anaux: 10 - 11. Body elongate; 3 primary color phases, the smallest with a black mid-lateral stripe which continues as pale red blotches on head; back above stripe yellow on reef fish and whitish on fish from inshore non-reef areas, and body below white. The largest phase, has a bright blue head and a green body with two broad vertical black bars anteriorly which are separated by a light blue interspace; this phase is always male. The small yellow phase with the black stripe may be either male or female (Ref. 13442).
Body shape (shape guide): fusiform / normal.
Inhabits reef areas, inshore bays and seagrass beds. Feeds mainly on zooplankton and small benthic animals, but may also feed on ectoparasites of other fishes (Ref. 9626). Spawn at midday throughout the year (Ref. 26938). A protogynous hermaphrodite (Ref. 55367). Generally of no interest to fisheries because of its small average size (Ref. 5217).
