How to tell it apart

Several striped grunts share these reefs and look similar at a glance. The black spot at the base of the tail fin is the mark that sets this species apart.

Appearance

Its body is silvery white, marked with orange-brown stripes that run along its length and are broader above the lateral line, the faint sensory line along its side. The head carries bronze-yellow stripes and spots, and the inside of the mouth is orange. Its tail fin is dark, while the anal, pectoral, and pelvic fins are clear. There is a black spot at the base of the tail fin.

Habitat

It lives on clear-water rocky and coral reefs and in mangroves across the western Atlantic, from Florida and the Bahamas through the Gulf of Mexico and the Caribbean Sea. Divers usually see it in schools at depths of 3 to 25 m.
