Parrotfishes (Scaridae) Overview
Parrotfishes are herbivorous and feed mainly on algae. They have beaklike dental plates that make it easy for them to scrape off algae from rocks and coral heads.
They usually have a pretty blue-green body and swim mainly with their pectoral fins. They can be difficult to spot in the water since they move fast.
In Hawaii, parrotfishes are also known as uhu, the juveniles as ‘ohua and mid-sized fish as panuhu. As they grow older they undergo color and sex changes.
