Regal Angelfish (Pygoplites diacanthus) Care
The Regal Angelfish, Pygoplites diacanthus, is also known as Royal Angelfish, Peacock Angelfish, and Empress Angelfish. They come from the Pacific Ocean, Indian Ocean, and the Red Sea regions. Adults are a bright yellow with thick white vertical stripes, a yellow tail, and gorgeous blue highlights. Juveniles are orange with vertical white bands edged in black, the dorsal fin is orange and the anal fin is yellow. Juveniles also have a large black ‘eye’ spot edged in white on the rear upper body.
Regal Angelfish are omnivores that require a diet of marine algae, sponges, angelfish food, and a variety of small meaty foods. They can be very picky eaters, which makes them a bit more difficult to keep. They do best in an aquarium that is at least 125 gallons or more and has plenty of live rock to graze on and hide in.
They are considered reef safe with caution because they are known to nip at clam mantles and corals.
The Regal Angelfish is territorial; it is recommended that they are introduced to a tank early so they can establish their territory first.
