About

The redmouth grouper is a serranid whose adults live on coastal reefs and in lagoons, favouring silty habitat and sheltering in or near caves and holes in the reef. It feeds mainly on small fishes, including sweepers of the genus Pempheris, and also takes mantis shrimps and other crustaceans. Its small juveniles are notable for mimicking two dwarf angelfishes, Centropyge vrolikii and C. nox, until they outgrow the disguise. Its range runs from the Red Sea and South Africa east to the Gilbert Islands, and it is recorded from tropical Indian Ocean islands and the Persian Gulf. It lives from 3 to 60 m, does not migrate, and is in season all year. It reaches about 60 cm total length, matures near 35 cm, and appears to spawn at any time of year. It is a minor commercial species and a game fish, selling in the highest price band, with a trophic level of 4.1, moderate to high fishing vulnerability at 49 of 100, moderate to high climate vulnerability at 50, and medium resilience.
