Holacanthus ciliaris also known as the Queen angel get there name from the speckled, blue-ringed black spot on their heads that resembles a crown. They are close relatives of the equally striking Blue angelfish (H. Bermudensis). To be found either alone or often in pairs in the warm waters of the Caribbean and western Atlantic.
Holacanthus ciliaris is decked with electric blue bodies, blazing yellow tails, and light purple and orange highlights, Queen angels are among the most strikingly colorful of all reef fishes. The Queen angel is a shy fish, fairly large for reef-dwellers, they can grow up to 45 centimeters in length. Like many other Angelfishes and Butterflyfishes, Queen Angelfish mate for life and are often found swimming in pairs.
The biggest issue you'll most likely encounter is feeding them. In the wild they mostly eat sponges but they will also nibble on sea fans, soft corals, and even jellyfish.. This can be near impossible to reproduce in the home aquarium, You don't want to add them to a new tank going through the nitrogen cycle or one without sufficient amounts of live rock.
