Scientific Name
Aethaloperca rogaa

Common Name
Redmouth grouper

Biology
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). In Hong Kong live fish markets (Ref. 27253).
