Size / Peso / Age
Maturity: Lm ? range ? - ? cm
Max length : 22.0 cm TL maschio/sesso non determinato; (Ref. 30573); common length : 18.0 cm TL maschio/sesso non determinato; (Ref. 30573)
Spine dorsali (totale) : 10; Raggi dorsali molli (totale) : 11; Spine anali: 3; Raggi anali molli: 6. Body yellowish with broad blackish stripe on upper side; head and anterior part of body with small dark reddish spots (Ref. 5469).Color changes with growth as well as varies among adults (Ref. 37816). In Oceania, juveniles are a golden green dorsally and white ventrally; in continental areas juveniles may be red dorsally (Ref. 37816). The maroon and yellow phase was originally described as a distinct species, P. typee (Ref. 37816).
Inhabits clear lagoon or seaward reefs to at least 33 m depth (Ref. 9710), but may venture very deep. Occurs openly on coral and soft-bottom habitats, occasionally in pairs (Ref. 48636). Benthic (Ref. 58302). Tends to perch on outermost branches of Stylophora, Pocillopora, and Acropora corals (Ref. 9710). Feeds mainly on small fishes and crustaceans, sometimes on shrimps and is territorial and haremic (Ref. 37816). Solitary on corals (Ref 90102). Marketed mostly fresh. Minimum depth reported taken from Ref. 128797.
