The Bicolor Angelfish is one of the larger dwarf angelfish. They’re semi-aggressive with most fish, but downright aggressive with other dwarf angelfish that are not mates. Dwarf angelfish and large angelfish are typically compatible, however. Use caution when housing this fish with corals; it may eat or damage corals, clams, and some inverts. Provide plenty of algae in its diet and also offer meaty foods like enriched Artemia, frozen mysis shrimp, and plankton.
Thought by many to be the most striking of the Centropyge group of dwarf or pygmy angelfish, the Bicolor Angelfish, also known as the Two-colored Angelfish or Oriole Angelfish, is a vibrant yellow on the anterior half of its body and a deep blue on the posterior half. A splash of deep blue extends upward vertically from the eye to the top of the head and the tail is yellow. A minimum of a 70 gallon tank with lots of hiding places and live rock for grazing will offer an environment in which to thrive. Not a good reef dweller, the Bicolor Angelfish is prone to nip at stony and soft corals (sessile invertebrates) and clam mantles. It is hermaphroditic, very difficult to breed in an aquarium, and has no distinguishable differences in color between male to female. The Bicolor Angelfish requires a diet of Spirulina , marine algae, high-quality angelfish preparations, and mysis or frozen shrimp.
