Bought this fish for my 180-gallon reef tank. It’s active and colorful, and hasn’t shown aggression toward other fish. Feeds well on algae wafers and small plankton. Needs a stable environment and regular water changes, but overall a great addition to the tank.

The fish is quite active and adds a lot of visual interest. I’ve had it for three months and it’s still healthy. It does require a larger tank, but the 150-gallon minimum is definitely necessary. Feeding is straightforward and it’s not overly aggressive.

Installed in a 200-gallon tank with corals and other fish. Acanthurus mata is peaceful with most species and helps control algae. It’s a bit shy at first but becomes more confident over time. Good for intermediate reef keepers.
