He swims for about 2 years in my 400 gallon tank and certainly harms corals. At first he may cause difficulties with food acception but that will stop rather fast. Has the peculiarity to only eat SPS corals from the bottom. He never attacks the growth part of the coral. He will eat corals for two weeks and then make a one week lasting pause in which the corals can recover. He will eat all other kind of food such as kiwis and bananas. during this time.
An impressive fish but only suitable for a fish tank or for aquariest with strong nerves who are not worried when he harms the corals.

Chaetodon xanthocephalus also commonly referred as the Yellowhead butterflyfish is widly distributed to the Western Indian Ocean from East Africa to Sri Lanka and the Maldives.
Chaetodon xanthocephalus overall color is white to pale grey with a series of five to six darker lines shaped in broad V's across the body. The head is covered by a broad yellow band and the dorsal and anal fins are mostly yellow. Grows to a maximum of 20cm long.
The Yellowhead butterflyfish is usaly found solitary but may form loose shoals of 5-6 individuals. Chaetodon xanthocephalus is very territorial and aggressive to other kinds of his genus.
Butterflyfish are not recommended for reefs as they will pick at or eat a wide variety of corals, fan worms, and other invertebrates. Most Butterflyfish are known to pick at Aiptaisia, a parasitic anemone.

Not reaching Andaman Sea, but curiously hybrid cross with this and C.ephippium common there; close to C.ephippium from the Pacific and head pattern of these greatly similar; hard to keep for a long period
