Natural History: The Regal Angelfishis found on clear lagoons, reef channels, and reef faces and dropoffs. It is observed to be reclusive, spending considerable times in caves and beneath overhangs. This species swims upside-down within caves. Juveniles are secretive and solitary while adults may be observed in pairs or haremic groups. Indian Ocean forms have yellow and orange on the breast and head while Pacific forms have blue and gray on those areas.
Husbandry: The Regal Angelfish is often shy when first added to the aquarium. It may be difficult to initiated feeding with this species. Mysid shrimp, opened clams, and live foods have been used with success. Numerous hiding places and a cave should be provided for this species. Live rock tends to increase the chances of acclimation by providing a natural food source. Bright lights tend to make it even more reclusive. It may later become aggressive toward other newly-added tankmates. It eats polyps from soft corals, stony corals, and zoanthids. It also naturally eats sponges and other invertebrates.
Reproduction: This species is reported to spirally ascend in water column and release gametes at the top of the ascent.
