Overview

Found singly, or in schools, over algal flats, rocky areas and seagrass beds of coral reefs.

Groupers are solitary carnivores that hunt near the bottom usually at dusk. Food is drawn into their mouths by a powerful suction when they open their overly large mouths and then swallowed whole.
Spawning is seasonal and controlled by the moons phase.
