The bicolor angelfish (Centropyge bicolor, also known as oriole angelfish) is a marine angelfish, with an easily recognisable yellow front and a dark blue rear completed with a yellow tail. This species is widely distributed in the South Pacific. The adult bicolor angelfish has a maximum size at just under 15 cm (6 inches) making it a relatively large member of the Centropyge (dwarf angelfish) genus. Despite being favored by many aquarists, the bicolor angelfish can be very difficult to keep; experts often find it difficult to keep them beyond an initial acclimatisation period.
