Color: The emperor angelfish is a rather beautiful fish. Its primary colors are blue and yellow. The eyes sport a mask. The back is striped blue and yellow lines. Be forewarned that like other large angelfish, adult fish may not reach the full color potential. A quality food supply with vitamin supplements and high water quality are necessary for the fish to reach the color as seen in these pictures.

Habitat: Provide with plenty of hiding places and live rock growth for grazing on and to use for shelter. Good water quality is important. Angelfish need good water quality for health and color retention.
Compatibility: Emperor angelfish in general can be kept with boxfish and moray eels and they should not be housed with sharks, rays and small non-aggressive fish such as firefish and cardinalfish and can be a problem if housed with many others – check with your aquarium shop if you plan on buying one of these fish.
