The Squaretail Coralgrouper is a robust grouper found in coral reef environments throughout the Indo-Pacific. Its name refers to the nearly square shape of its tail fin, a reliable field mark. Like other large groupers, it hunts by ambush, lying among coral heads and rocky outcrops before lunging at passing prey. Divers typically encounter this species at moderate depths among branching corals and reef structures.
