I’ve had my Acanthurus mata for six months now. It’s active and stays in the middle of the tank. The fish is not overly aggressive and doesn’t bother the corals. It’s a good addition to a 150-gallon reef setup. Feeding is easy with spirulina and marine flakes.

The fish grows steadily and has adapted well to the tank. It’s semi-aggressive but doesn’t cause issues with other fish. I noticed it’s more active during the day. Needs a good hiding spot, which I provided with a rock crevice.

Great choice for intermediate reef keepers. It’s hardy and doesn’t damage the reef. I’ve seen it swim in patterns and interact with other fish without conflict. The size range of 3 to 4 inches is perfect for a medium tank.
