Description

The highfin coral trout is a large grouper (Epinephelidae) from the western Pacific. The species grows to about 75 cm and has a red-brown body studded with blue spots and lines. As a fast reef predator it actively hunts small fish and crustaceans by day. Although a valued food fish, large coral trout are among the known ciguatera carriers and large specimens should not be eaten. The fish is harmless to humans in contact.
