Green Parrot Wrassefish

Green Parrot Wrassefish

Green Parrot Wrassefish are noted for their bright, parrot-like colors (predominantly red and green) and their sharp beaks with which they scrape dead coral and rock to feed on algae. On most coral reefs you can find the bite marks of these fish, where they have scraped off some of the coral in their quest for algae, pulverizing the hard calcarious material with their teeth. All coral sediment that is ingested is eliminated as sand. It is estimated that, around coral reefs, approximately one ton per acre per year of sand is produced by coral material that has passed through Parrotfish.
