The Regal Angelfish, Pygoplites diacanthus

Of the many species of marine angelfishes offered to the hobby, some groups are sure winners. Most "dwarf angels (e.g. the genera Centropyge and Genicanthus) readily accept aquarium conditions, eagerly eat all types of prepared foods, exhibit good disease resistance and stay reasonably small and non-aggressive. The same can be said for many of the larger Pacific and Atlantic angels. Except for getting too large for undersized systems various Pomacanthus (e.g. French, Gray, Emperor, Koran), Holacanthus (e.g. king or Passer's, Queen, Blue), Apolemichthys (e.g. A. xanthurus, the Indian Yellow-Tailed Angel) are generally quite hardy and easy to keep in captive conditions as long as provided with sufficient tank space, food, and water quality.
The Regal Angel, Pygoplites diacanthus, is our notable exception. It is indeed unfortunate that such a beauty rarely accepts food in captivity. In this article I'll gladly offer you insights as to what has "worked" with this angel and other members of the family.
The Group: Family Pomacanthidae
There are about eighty five described species of marine angels, in nine recognized genera; Pygoplites being monotypic, that is having only the one species, P. diacanthus. At any moment some twenty or so angels are offered in the ornamental trade with twice that number available annually. The present subject, the regal is, in my opinion, too often found; sold to the unwary aquarist by less-than-knowledgeable dealers.
Pomacanthids are found worldwide in tropical seas in shallow to six-hundred foot depths. They are closely related to butterflyfishes from which pomacanthids can be separated on the basis of possessing a prominent cheek spine (-acanthus) which butterflies lack.
Pygoplites diacanthus (Boddaert 1772), the Regal Angelfish. Indo-Pacific; Red Sea, East Africa to the Tuamotus, north to southern Japan. To ten inches in length. Note the gray chest area of this Fijian specimen. The more desirable, hardier Indian Ocean and Red Sea ones have an orange chest area. Below, tiny 2 and 3 cm. specimens photographed in captivity by Hiroyuki Tanaka.
Habitat:
Regal angels are found ranging widely over rich coral areas, ducking in and out of crevices. These sheltering caverns are always places of good circulation.
Water quality. I acknowledge Hemdal with pointing out that angels be introduced to established systems only. They do not weather nitrogen cycling changes well. Wait till the aquarium has been set up a good three to four months before introducing angels. Gunther Dawal in Prof. Ladiges Aquarium Digest International piece credits strong water circulation and frequent water changes with his success with Pygoplites.
Tank size should be at least four feet in length, sixty-plus gallons for even a small regal. They attain a length of about a foot in captivity, two in the wild.
Foods/Feeding:
An important factor in failure and success in keeping angels. I recommend at least once daily an offering of a meaty food; chopped fresh or frozen clam, crab, shrimp, squid... and some source of greenery. Marine algae are best; you can grow some of these, others can be purchased from the oriental section at your food store. Lettuce made mushy by freezing, spinach, husked peas are used by some. Some personal acquaintances that have had success keeping regals on more standard fare advise avoiding gelatin-based frozen foods. There are excellent preparations made without gelatin and these are much better for your angels. Check the labels for ingredients.
Live rock and dry-prepared foods are accepted often, but should not be considered staples. Live saltwater foods are unnecessary for marine angels and too easily introduce disease. Stick with frozen.
Refusing food for a few days should not overly concern you; however large angels do have hearty appetites. Feeding strikes cal for water changes, vitamin-based feeding stimulants and a switch-up in foods offered. A fresh opened shellfish often works wonders. Your specimens ought to have an overall plump appearance when in good condition. San Francisco Bay Brands are excellent.
Our most problematic area with regal angels is nutrition. Pygoplites feeds almost exclusively on tunicates (sea squirts) and sponges in the wild. Allen and Steene (1979) give this species their most difficult species rating for the amount of care required.
