Habitat: Marine. Shallow coral reefs and related inshore habitats such as sea grass beds, at depths of 6-65 feet (2-20m). Juveniles common in very shallow areas like seagrass beds and generally associated to some shelter such as coral heads or rocks, where potential food sources like algae and encrusting invertebrates can grow. Natural History Notes: Feed principally on tentacles of polychaetes worms, coral polyps and zoantharians (colonial sea anemones). Adults live in pairs while the young are usually solitary. If an adult pair gets separated the each partner will try to find and join the other. Diurnal. Seeks shelter at the end of the day in order to rest and to hide from any possible predators such as moray eels and sharks. It has been presumed that the large ocellated black spot is a false eye; this plus the obliterative black bar through the eye supposedly results in a predator confusing the back end of the fish for the front. Diurnal. Characteristics: Adults : round black eye-spot on rear body near upper base of tail surronded by a brillant white. Narrow dark lines along the scales rows. Scales running up and back above mid body and down and back below midbody. Juveniles : two eye spots, the one that desappears placed on the lobe of the soft dorsal fin. Two broad dusky bands on the body.
