The species grows to about 12 cm and has a greenish to brown body with fine lines and spots on the head and an eyespot on the dorsal fin. It usually occurs in groups on shallow coastal reefs and seagrass flats, also in areas of algae, rocks and lagoons. On the bottom it forages on small invertebrates.
