The Diadem Dottyback is a striking addition to my reef tank. It’s active and adds a lot of visual appeal. I’ve had it for six months and it’s still healthy and curious. Water parameters are stable, and it doesn’t stress the corals.

Great fish with a unique pattern. It’s not overly aggressive and fits well with my clownfish and anemones. I do need to monitor water flow to keep it happy.
