Description
The Yellowfin Surgeonfish is a large, robust tang known for its distinctive yellow pectoral fins and a prominent yellow spot around the eye. Its body coloration can vary from grey to brownish-blue, often with a subtle blue line along the dorsal fin base and a purplish caudal fin. This species is a voracious algae grazer, making it beneficial for controlling nuisance algae in large reef or fish-only aquariums.
