Environment: milieu / climate zone / depth range / distribution range
Écologie
marin récifal; profondeur 0 - 180 m (Ref. 9710), usually 0 - 25 m (Ref. 90102). Tropical; 22°C - 27°C (Ref. 27115); 30°N - 23°S
Pacific Ocean: Indonesia to Samoa, north to Ryukyu Islands, south to New Caledonia and the Rowley Shoals in the eastern Indian Ocean (Ref. 1602) and Christmas Island (Ref. 114977).
Taille / Poids / Âge
Maturity: Lm ? range ? - ? cm
Max length : 20.0 cm TL mâle / non sexé; (Ref. 9710)
Épines dorsales (Total) : 10; Rayons mous dorsaux (Total) : 16 - 18; Épines anales: 3; Rayons mous anaux: 6 - 7. Highly variable in color and also in the size of the pale blotch (looks blue in natural light). Latter varied from being totally absent to an area almost half the body size, especially when showing nuptial colors. At the Rowley Shoals, off the north-western Australian coast, it only shows the blotch when nuptial (Ref. 48635).
Aggregations of this species occur a few meters above the edges of current-swept drop-offs (Ref. 4538). Females and males in separate aggregations or mixed sexes (Ref. 48635). Juveniles solitary and remain close to shelter (Ref. 37816). Seldom encountered in the aquarium trade (Ref. 1602).
