Parrotfish are a large family of marine fish made up of over 90 distinct species. They are characterized by their parrot-like beaks which are made of tightly compressed teeth. In the wild parrotfish use their beak-like mouths to scrape algae off corals. Adult parrotfish often bite off large pieces of coral when feeding in this way and contribute greatly to bioerosion in coral reefs around the world. Although a peaceful and extremely beautiful species of fish, their highly specific dietary requirements make them unsuitable for beginner and novice aquarists. Most species are vibrantly colored and are adorned with fascinating color patterns and markings. They come in shades of red, blue, green, yellow, orange, grey and black.
