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 other tank mates. I appreciate the reef compatibility. Only thing is it needs a large tank and stable water conditions.

The fish looks great and is a good addition to my 150-gallon reef tank. It’s semi-aggressive but doesn’t cause issues with other fish. I’ve noticed it spends time near the edges and occasionally swims in groups. Needs consistent water parameters to thrive.

This species is a striking addition to the tank. It’s active and helps with algae control. I’ve kept it with corals and it hasn’t damaged any. The only challenge is the space requirement—must have a large tank.
