The Regal Angelfish (Pygoplites diacanthus) is also known as the Royal Angelfish. It is one of those species that is highly sought after by more advanced saltwater aquarium keepers. It comes with a long track record of being known as hard to keep. They are also highly sought after because of their looks. They are jaw dropping beautiful.
However, they should be avoided by most hobbyists because they do not adapt well to aquarium life. If you do decide to get one of these regals make sure you see them eating in the store first! Try to get one originating from the Indian Ocean instead of the Indo-Pacific. The Indian Ocean species seem to be able to adapt better to aquariums and feeding than their Indo-Pacific counterparts.
The Regal Angelfish is being sold for around $75 to $250 depending on size and location collected. Since the Indian Ocean regals are adapting better they are going for higher prices.
Seriously consider taking a pass on this species unless you feel completely confident in your abilities to get them eating.
