Western Pacific: southern Japan to Australia (Queensland and Western Australia) and eastward to the Caroline Islands and Fiji. Recently recorded from Tonga (Ref. 53797). Often misidentified as Plectropomus maculatus.
Inhabit coral-rich areas of lagoon reefs and mid-shelf reefs (Ref. 6390, 48635). Solitary (Ref 90102). Inactive at night, hiding under ledges (Ref. 9710). Juveniles have a demersal existence in shallow water in reef habitats, especially around coral rubble (Ref. 27259). Adults feed mainly on fish (Ref. 6390). Juveniles feed on small fish and invertebrates such as crustaceans and squid (Ref. 27261). A protogynous hermaphrodite (Ref. 55367). Form several spawning aggregations on a reef occurring around the new moon (Ref. 27259). Eggs float just below the surface (Ref. 6390). Larvae are pelagic (Ref. 6390). P. leopardus is used in cage culture; P. maculatus in Ref. 3081 was probably a mixture of P. maculatus and P. leopardus; the Plectropomus sp. used for the experiments reported in Ref. 4719 consisted predominantly of P. leopardus, with some P. maculatus (M.F. Capra, pers. comm.). On the Great Barrier Reef, its maximum lifespan is 14 years (Ref. 37816).
A monandric species (Ref. 55367) but now confirmed for diandry (Ref. 103751). Sex change occurs at 32.1 cm TL and 16 years of age (Ref. 55367).
Courtship behavior: a male approaches 1 or more females from behind, changing color from dark brown to brownish white while the edges of median fins remained dark. As the male gets near, it flicks its dorsal and pelvic fins eliciting a mild lateral display from the female. The male rolls onto its side and shakes from side to side as its abdomen passes the female. Takes 15 seconds (Ref. 2160).
