Now there seem to be a number of different names and variations of this beauty, it is also called the Rip Butterflyfish in some books, for clarity, this post relates to Chaetodon Trifasciatus.
Often seen in pairs and in very shallow water, this stunning golden round fish feed on coral polyps and are common in both the Indian Ocean and the Andaman sea. A slightly more yellow variation can be spotted in the Red Sea and has a different classification but similar appearance.
They can grow up to 15cm in size are always found in areas of rich coral growth. Juvenile Oval Butterflyfish are much paler, missing a lot of the black markings and the totally round shape. An ideal photo target due to their striking colours and numbers in the shallows.
