| Found in coastal reefs and lagoons, often silty habitat (Ref. 48635), in or near caves and holes in the reef. Feeds mainly on small fishes (including Pempheris sp.), also on stomatopods (Pseudosquilla sp.) (Ref. 6448); and crustaceans (Ref. 37816). Preliminary data indicate that it spawns at any time of the year and matures (females?) at about 35 cm SL (Ref. 6448). Small juveniles mimic Centropyge vrolikii (Ref. 8631), and C. nox until they outgrow their model in size (Ref. 48635). Taken as part of the live reef food fish trade centered in China and In Hong Kong; occasionally found in markets (Ref. 89707). |
