Care
So named because of its striking blue and yellow colouration, the Bicolor Angelfish is best housed in mature tanks containing plenty of live rock which will provide this delicate fish with constant grazing opportunities and a myriad of hiding places. Unfortunately it is not always a good choice for the reef aquarium as many corals and other inverts will be nipped at, although some experts regard them as being safe with mushroom polyps (e.g. Actinodiscus, Rhodactis and Discosoma species). Unless you have a tank of vast proportions with a profusion of rockwork, this really should be the only angelfish added to the aquarium. If a group is desired in such a huge show tank, then a good sized group of juveniles should be added simultaneously, as the last species added to the aquarium. However, consideration must be given to the amount of available natural food (microalgae) within the tank, and if it will have time to keep replenishing under the attentions of such a group of fish with a taste for the green stuff. Tankmates must also be of similar size and temperament to adult Bicolour Angelfish. Large boisterous fish will send the angelfish into hiding, and there is a possibility that fish smaller and more placid than the angel may be continuously chased about (although with the latter, this is not always the case - particularly in a large tank "“ but individual personalities do vary).
Feeding
Offer a varied diet which includes frozen foods containing Spirulina, vitamin-enriched brineshrimp, Mysis shrimp, finely chopped shrimp etc, plus marine flake food and greens, including Nori. Does best in mature aquaria with a healthy microalgae growth. Frozen rations prepared especially for angelfish are good if you can find them. Garlic additives are excellent for those specimens that appear a little reluctant to take prepared foods, although you should always check with your dealer that your angelfish is feeding prior to purchase. Feed small amounts 2-3 times per day and if you have space in a well lit sump, filamentous algae can be cultured on pieces of rock, and occasionally rotated with some of the pieces in the main display aquarium.
Breeding
In the wild, this species is a haremic spawner, one dominant male spawning with several females. Spawning is normally triggered by an environmental cue, and the fertilised eggs float up to the surface, where after a time the young will begin their lives feeding on microscopic plankton.
