[edit] Sexing

It is difficult to visually sex these fish.

[edit] Tank compatibility

This is a large Angelfish that will be aggressive towards other Angelfish or fish of the same shape. They are generally not reef safe with delicate soft corals, but tougher SPS corals are a possibility with caution. Do not keep with small tankmates that look as though they could be a mouth-full, as chances are, they will get munched.

[edit] Diet

They should be fed Spirulina, marine algae, high-quality angelfish preparations, mysid or frozen shrimp, and other meaty foods.

[edit] Feeding regime

Feed once or twice a day.

[edit] Environment Specifics

They require a spacious light tank with plenty of swimming and growing room for this large fish. They will need hiding places provided.

[edit] Behaviour

A large and territorial fish, they will become quite dominant within a tank environment.

[edit] Identification

A large oval-shaped and laterally depressed fish. As with many Angelfish, juvenile colouration is completely different to adults. Juveniles are black with circular white and blue stripes starting at the tail. Adults have a bold, blue body covered with bright yellow horizontal stripes culminating in a bright yellow to orange caudal fin. There is a blue-black "mask" covering the eyes, a similarly-coloured vertical band extends from the pectoral fin two-thirds of the way up the body. This band is highlighted in sapphire-blue in front, and bright yellow, caudally. The mouth is white.
