The bicolor angelfish is a dwarf angelfish species that is widespread throughout the Indo-Pacific. These fish can be spotted from Malaysia to northwestern Australia, Japan, and Samoa in waters from depths of 3 to 82 ft (1 to 25 m). They prefer areas of rich coral growth on seaward facing reefs. They also occur in rubble areas. They are named for their striking two color body and are easily recognized by their yellow tail, yellow front half, and blue rear with blue patterns above and around each eye. Males and females have the same colors. Like other angelfish species,
the bicolor angelfish has a compressed body and possesses a large spine at the front corner of each gill cover. The fish feed on algae and many different invertebrates with their mouth full of brushlike teeth. They swim close to the bottom while grazing, but they never go far from the shelter of reef crevices. They may occur singly, in pairs, or small aggregations. For reproduction, they typically form harems with one male and several females. The largest female is able to change into a male if a male in the group dies or is removed. Spawning normally occurs at dusk,
with the eggs floating and being dispersed by the current. Young initially feed on plankton. Adults can grow to about 5 in (12.5 cm) long. Bicolor angelfish are highly sought-after by aquarium hobbyists because of their vibrant colors, relatively small adult sizes and quick adaptation to captive environments.
