With its vivid coloration and pattern, the Regal Angelfish makes a beautiful addition to a saltwaterfish aquarium. It features a distinctive yellow belly that is more difficult to maintain than other angel species. Make sure to introduce the Regal Angelfish first so that it may stake out its territory in advance of other fish. It can grow up to 10 inches and should be kept in a tank of less than 75 gallons along with plenty of hiding places and live rocks for grazing. The Regal Angelfish also requires extensive rockwork and deep caves to feel secure. The adult Regal Angelfish may found nipping at stony and soft corals, clam mantles, but doesn?t disturb other small polyped stony corals. It is considered reef safe but with caution. It should be fed a diet of Spirulina, marine algae, high-quality angelfish preparations, mysis or frozen shrimp, and other meaty items. The Regal Angelfish thrives well in a temperature range of 72-78 degrees Fahrenheit and pH of 8.1-8.4. The Regal Angelfish is semi-aggressive and should not be housed with puffers, hawk fishes and predatory fishes. The Regal Angelfish requires high care and is difficult to maintain in the tank, that is why it should only be kept by experienced aquarist. It's one fish that almost requires a quarantine period in order to become used to aquarium conditions and be treated medicinally if necessary. We suggest a quarantine tank of not less than 20 gallons with a few hiding places created from PVC pipes or fittings.
