Description
A large, iconic Indo-Pacific angelfish whose adults wear a deep blue body crossed by dozens of narrow yellow horizontal stripes, a black eye mask edged in electric blue, and a yellow tail, a dramatic change from the concentric blue-and-white ring pattern of juveniles. It is a bold, semi-aggressive centerpiece fish that should be kept one per tank, added last, and given extensive rockwork with deep caves plus at least six feet of swimming length. Adults nip stony and soft corals, clam mantles, and other sessile invertebrates, so it is best suited to large FOWLR systems or carefully chosen mixed reefs, and it needs a varied sponge-supplemented diet fed several times daily to hold its color.

With caution
Environment
The Emperor Angelfish requires a large tank with plenty of hiding places and live rock for grazing. They prefer a well-lit tank with moderate to strong water movement.
Behavior
This species is semi-aggressive. It can be territorial and will defend its space against others. It is generally peaceful with other species if they are not similar in shape and color.

Incredibly beautiful fish, can be quite aggressive, I’d say one of the more aggressive large angelfish. Never touched coral but feed them very well in case.
