About Chaetodon andamanensis Kuiter & Debelius, 1999
Chaetodon andamanensis is primarily bright yellow in color. It has a black band that runs from the top of its head through its eyes, and a black ocellus on its caudal peduncle. Its dorsal fin contains 14 spines and 18 soft rays, while its anal fin has 4 spines and 16 to 18 soft rays. This species reaches a maximum total length of 15 centimetres, or 5.9 inches. This species is distributed in the eastern Indian Ocean. It has been recorded from Sri Lanka, southwestern India, the Andaman Islands, the Nicobar Islands, the Maldives, the Mergui Archipelago in Myanmar, the Similan Islands of Thailand, and Weh Island off northwestern Sumatra in Indonesia. Chaetodon andamanensis inhabits rock or coral reef habitats near the shoreline or on outer reef slopes. Individuals may be solitary, but they are most often found in pairs or small groups. Their diet consists mainly of coral polyps. This is an oviparous species that forms breeding pairs. It is thought to be a slow-breeding fish that requires live branching coral to reproduce. It occurs at depths between 1 and 10 metres, or 3.3 and 32.8 feet.
