Widespread Indo-Pacific
Butterflyfish and Angelfish are members of the bristletooth family (Chaetodontidae) they have very fine hairlike teeth that enable them to pick out small organisms inaccessible to most other fish for eating.
Butterflyfishes thrive on a diet of coral polyps, tentacles of featherdusters and Christmas-tree worms. As these food sources all zap back into their shells the butterflyfishes need to be able to hover motionless while picking at the coral and to dart swiftly over short distances to get the worm before it retracts. They do this by using their Pectoral fins as oars to brake, sprint, turn and even reverse.

This fish appears to be a FULL grown adult. All the lines are complete with no forking or breaks. compare to the others shown here, although the pics are not fantastic they all represent a slightly different age. with a few more pictures we should be able to tell just how old they are, so please keep adding.
