Regal Angelfish

Regal Angelfish, scientifically named Pygoplites diacanthus, is also known as the Royal Angelfish.

It’s a type of marine fish with ray-like fins. It belongs to the Pomacanthidae family and the unique genus Pygoplites.

This fish is found in tropical Indo-Pacific oceans and can grow up to 25 cm (about 9.8 inches) in length.

Regal angelfish is typically found in coral-rich areas of lagoons and seaward reefs, at depths of up to 48 meters (about 157 feet) or more.

They are often seen near caves and feed on sponges and tunicates. These fish can be found alone, in pairs, or in groups.

They are frequently exported for the aquarium trade, but they rarely survive well in aquariums.

Regal angelfish is not considered reef safe, meaning that if introduced into an aquarium environment, it can potentially harm coral reefs.
