The blue parrotfish (Scarus coeruleus) is a vibrant, uniformly blue fish that lives in the tropical and subtropical waters of the Atlantic Ocean, particularly around the Caribbean and the western Atlantic coasts. Named for its beak-like mouth, the blue parrotfish uses this structure to scrape algae off rocks and coral, which is a primary part of its diet. In doing so, it plays a crucial role in maintaining reef health by preventing algae overgrowth and contributing to sand production through the breakdown of coral fragments.

This species is known for its gentle, grazing behavior and social nature, often seen swimming in schools around coral reefs. The bright, turquoise-blue color of adult blue parrotfish makes them easily recognizable, while juveniles can be lighter with yellow or white patches.

Despite their hardiness in the wild, blue parrotfish aren’t commonly kept in aquariums due to their size (up to 3-4 feet long) and specific dietary needs. They require extensive habitats to thrive, making them best appreciated in the wild or in large, specialized aquariums dedicated to showcasing reef ecosystems.
