Bought this dottyback for my 35-gallon reef tank. It’s active and colorful, and has adapted well to the environment. I noticed it’s slightly territorial with smaller shrimp, so I added some rock cover. Overall, a great beginner-friendly fish.

The fish arrived healthy and grew nicely in the first few weeks. It’s not overly aggressive, just watches the tank with interest. I keep it with a group of tangs and it seems to coexist well.

Perfect for a beginner reef setup. The fish is vibrant and stays active. I’ve had it for three months now and it’s still thriving. Only needed to adjust lighting slightly to match its activity pattern.
