The Bicolor Angel a.k.a Oriole Angel, is a beautiful dwarf angel that is colored in contrasts of bright yellow and deep blue. The forebody is yellow with a blue saddle across its nape and the rearbody is blue with a bright yellow tailfin. Bicolor fish are collected at shallow, coral-rich reefs. They do very well in aquariums and prefer lots of rockwork to feel comfortable. The Bicolor Angelfish has no distinguishable differences in color between male to female. The Bicolor Angelfish should be kept in a tank of 50 gallons or larger with plenty of places to hide and swim , so it'll have ample room to roam. Keep water quality high (SG 1.020 - 1.025, pH 8.1 - 8.4, Temp. 72 - 78° F).They will spend most of their day grazing algae that grows on live rock. The Bicolor Angelfish groups up to 6 Inches in size. The Dwarf Bicolor Angelfish may come in 2 to 4 inches in size generally.
Bicolor Angelfish are yellow anteriorly and blue posteriorly. There is a blue bar above the eyes and the caudal fin is yellow. This species grows to 15cm in length. Bicolor Angelfish inhabit rubbly areas in lagoons and on reef slopes. They use crevices in the reef for shelter. This fish is commonly seen singly, in pairs or in small aggregations. It is found in depths from 3m to 25m. The Bicolor Angelfish feeds on algae, small crustaceans and worms close to the bottom.
Origin: Coral Sea, New Caledonia, Fiji Common in the Great Barrier Reef and New Guinea. They are are widespread throughout most of the Pacific Ocean. However, Bicolor Angels are not found in Hawaii.
Specific Care Information: Dwarf Angelfish are generally peaceful fish but will often quarrel with members of their own species and even genus if they look similar enough. Though there are reports generalizing this species are 'reef safe', we strongly advise to add them to a reef with extreme caution. The reason for this is that many of this species will behave like model citizens for a while, but one day will go after corals and clams for no reason. This may have something to do with the Dwarf Angelfish being predominately plankton eaters as juveniles. An underfed adult may attempt to try something new and find that clams and corals are it's newest favorite diet. We recommend purchasing the youngest specimen available in hopes it settles down and learns to eat a captive diet prior to learning that corals and clams are a tasty treat.
It is important to provide Dwarf Angelfish with plenty of good quality cured live rock and a well aquascaped aquarium with caves, archways and overhangs to swim through or hide in. Especially if there will be more than one Dwarf Angelfish in the same aquarium. Members of the Centropyge genus are referred to as Dwarf Angelfish because of their smaller size in relation to their larger Chaetodontoplus, Genicanthus, Holacanthus and Pomacanthus cousins.
Diet: In the wild the Bicolor angelfish has a varied diet consisting of algae and crustaceans. The Bicolor angel is not considered reef safe as it may nip at large polyped stony corals, soft corals, zoanthids and clam mantles. There are occasional specimens that live very long lives in reef aquaria as peaceful citizens but the majority of these fish will often turn for no apparent reason when they are older. This may be easily explained as many of the Centropyge family are predominately plankton eaters as juveniles and will switch to consuming it’s natural adult diet once fully grown. Sometimes all it takes is for an underfed individual to ‘test’ a food source. This being the case, be sure to add this specimen to a well established tank and feed frozen mysis shrimp, meaty crustaceans such as shrimp and clam. Be sure to include algae such as spirulina.
Average lifespan: Bicolor Angelfish has an Average Lifespan of 12 years
Breeding and Propagation: Bicolor Angels begin their lives as an indeterminate sex, before becoming female. Females may turn into males as they develop. In a group of females without a male, an adult female may become a male. Many Bicolor Angels breed when one releases a gamete, or sex cell, which induces a courtship display of swimming, then spawning, then chasing each other. Because the fry of most Angels are planktonic in nature, they have proven extremely difficult to raise.
