This tang has been in my 100-gallon reef tank for six months. It’s active and doesn’t harm the corals. Feeds well on algae and shows good coloration. Only needs occasional cleaning of its gill area. A solid addition to a mid-sized reef setup.

The fish arrived healthy and has adapted well to the tank. It’s semi-aggressive but doesn’t attack other fish. I’ve noticed it spends time near the back wall, which is good for visibility. Needs a good flow and plenty of hiding spots.

Great color and active behavior. I’ve kept it with other tangs and it coexists peacefully. The tank is now more dynamic with daily movement. Only issue is it occasionally nips at smaller invertebrates, but that’s common for this species.
