Keyhole Angel (Asia Pacific)
The Keyhole angel is overall an intense dark black with what appears to be a bright light shining through a hole in its side, like the light from a keyhole in a door. Its lower fins are dipped in a lovely lemony yellow. Males and females are visually identical.
The Keyhole angel can grow to be up to 8 inches long and needs an aquarium of at least 125 gallons. It does not appreciate living with other angelfish and may become aggressive to them, however it is typically non-aggressive with other types of fish. If several dwarf angelfish are to be kept together the aquarium must be large enough and they must all be added at the same time.
Angelfish may nip on many types of corals, especially LPS corals, clam mantles, sponges, and sometimes soft corals. They do not typically bother other types of invertebrates. They feel most secure when there is plenty of live rock to hide in, as well as open space for swimming. Diet should include plenty of marine algae and Spirulina, Sponge matter, frozen Mysis shrimp, half shell clams, and other high quality meaty items. It should be fed 2-3 times a day. It has been known to eat filamentous and diatom algae in the aquarium.
