Geography / Habitat: The Keyhole Angelfish inhabit the Western Pacific Ocean and the Eastern Indian Ocean. They are found in areas of Christmas Island to Fiji then northward to the southern part of Japan.and southward to the Scott Reef, the Eastern Indian Ocean, and Lord Howe Island. The Keyhole Angelfish are found alone or in harems of 3-7 individuals. They inhabit mixed coral and rubble areas of lagoons and seaward reefs, feeding primarily on algae and some and crustaceans. The depths they are found as adults is from 13 to 180 feet (4 to 55 m). Life Strategy: If an Angelfish suddenly displays a bulging belly and a more aggressive behaviour, it is probably a gravid female Angelfish. Two Angelfish grooming each other is also a typical breeding behaviour. Angelfish of both sexes will also flash fins, face off, lock their mouths and twist around. When a couple has been formed, they will choose a spawning site and start cleaning it together. The Angelfish eggs will be deposited on the spawning slate and placed in very neat and evenly spaced lines. If she doesn’t like the spawning slate, she will deposit the eggs somewhere else in the aquarium. The male Angelfish will fertilize the eggs by following close behind the female and touching all the eggs with his papilla. If you keep only female Angelfish, one of the females might actually resume a male behaviour and follow the egg-laying female and touch the eggs. Those eggs will naturally remain unfertilized and become white within a few days. Food / Feed Strategy: The Keyhole Angelfish is an omnivore. In the wild their diet mainly consists of algae along with some crustaceans. They need algae naturally growing in the tank to be healthy. Feeding them several times a day and offering a variety of good foods is important even with amply algae in the tank. These include prepared foods with marine algae, spirulina enriched foods, frozen mysid shrimp, brine shrimp, and meaty crustaceans such as shaved shrimp and clams. There are several good commercial foods available including Formula II and Angel Formula. Body Form or Style: The Keyhole Angelfish has the typical shape for a dwarf species, having a small elongated oval shaped body with rounded fins. This dwarf angelfish ranges in overall color from dark bluish black to black. It has a vertical white oval blotch on the upper back below the dorsal fin toward the front, giving it rise to its common name.
