Common Coral Trout vary from red to greenish brown and are covered with a profusion of small blue dots over the body and all fins except the pectoral fins, which are transparent. Colour can vary with time of day, habitat and the activity of the fish. There is a distinctive blue ring around the eye. The soft dorsal fin is rounded and the lunate tail often has a fine white margin. They have a large mouth and sharp widely spaced canine teeth.
