Yellowfin Tang – LiveAquaria
The Yellowfin Tang, also known as the Yellow-Mask Surgeonfish, is the largest of the Acanthurus genus, ideal for grand show displays and public aquariums. Coloration varies widely between juveniles and adults, with younger fish exhibiting yellow fins which morph to a dullish purple as they mature.
In its natural habitat, the Yellowfin Tang can be found widely distributed in waters ranging from 3 to 300 feet. A 360 gallon or larger established aquarium with large amounts of live rock is necessary to provide both plenty of swimming room and territories within the live rock.
Although tangs will eat meaty foods along with the other fish in the aquarium, it is important that they are offered plenty of marine based seaweed and algae. This will support their health and help maintain a balanced tank environment.

The Yellowfin Tang is a striking addition to my 400-gallon reef tank. It’s active and curious, and the color change from yellow to purple is fascinating to watch. I feed it daily with spirulina and algae sheets, and it seems to thrive in the established environment.

This fish is impressive in size and appearance. After a few months, the color shift from juvenile to adult phase became clear. I made sure to include plenty of live rock and algae to keep it happy and healthy.

Great choice for a large display tank. The fish is calm and doesn’t dominate the space. I noticed it spends time grazing on the algae-covered rock, which helps maintain the tank’s cleanliness.
