King angelfish

The king angelfish is a large marine angelfish of the family Pomacanthidae, found in the eastern Pacific from the Gulf of California to Peru, including the Galapagos. Adults are deep blue to blue-gray with a bright orange tail and a distinctive vertical white bar behind the head, and long trailing fin filaments. It is a bold, semi-aggressive fish that becomes territorial with age and is best kept singly with robust tankmates in a spacious tank. A very large aquarium with abundant live rock provides both grazing and hiding space. It is an omnivore that in the wild feeds heavily on sponges and also acts as a cleaner when young; captive diet should include sponge-based angel preparations, marine algae and meaty foods. It prefers slightly cooler subtropical water than most tropical angels. It is generally not reef-safe, as it nips corals and clam mantles.
