Description
A massive, deep-bodied surgeonfish with a purplish-grey body, a dull yellow band in front of the eye, and yellow outer thirds to the pectoral fins; juveniles are far more yellow overall and darken with age. It is an active, semi-aggressive grazer that will bully smaller tangs and any similarly shaped fish, so it needs a very large, open-swimming display with plenty of rockwork territory and should be added last. It grazes constantly on film and filamentous algae and will not harm corals, but its adult bulk and appetite make it a fish for show-sized or public-aquarium systems only.
Reef Safe
Yes
Environment

Behavior
Yellowfin Tangs are active swimmers and need plenty of space to roam. They can be territorial, especially with other tangs, and may show aggression if not provided with enough space.
