Queen Angelfish [Some Very Interesting Facts]

Queen Angelfish

Queen Angelfish, scientifically named Holacanthus ciliaris, is a colorful marine fish found in the western Atlantic Ocean.

It’s also known as the Blue Angelfish, Golden Angelfish, or Yellow Angelfish.

This warm-water species lives near the ocean floor in coral reefs and is recognized by its blue and yellow colors and a unique spot or “crown” on its forehead.

The crown helps differentiate it from the similar-looking Bermuda Blue Angelfish. Adult queen angelfish mostly eat sponges.

They live in a territory where females forage separately and are taken care of by males.

Young queen angelfish have different colors than adults and act as cleaner fish, picking parasites off other fish.

This species is popular in the aquarium trade and has been commonly exported from Brazil.

In 2010, the International Union for Conservation of Nature assessed the queen angelfish as “Least Concern,” meaning the wild population seemed stable.

They are usually found alone or in pairs, gracefully moving among sea fans, sea whips, and corals.

Their diet mainly consists of sponges, with some algae, tunicates, hydroids, and bryozoans.

However, they are not considered reef safe, meaning they can potentially harm coral reefs when introduced into a reef tank.
