Rainbow Parrotfish
Scarus guacamaiaAlso known as Guacamaia
Rainbow parrotfish are among the largest herbivorous fish in the Atlantic, instantly recognizable by their vibrant orange-bronze heads and brilliant green-blue bodies. They play a vital role in reef health by scraping algae from corals with their fused, beak-like teeth, grinding down limestone into fine white sand. Young fish rely heavily on coastal mangrove forests for shelter before migrating to offshore coral reefs as adults.
