Easy to care for as a beginner fish. It’s active and colorful, especially when the algae in the tank is abundant. The coloration is vibrant and changes slightly over time. I’ve kept it for over a year and it’s still healthy and social with other reef fish.

Grew quickly from a small size to medium. Needs a good amount of algae to stay happy. I added a few algae sheets and it’s been feeding well. Not aggressive, just enjoys the reef environment.

Beautiful fish with a unique rounded shape. The color patterns are quite striking, especially under medium lighting. It’s a great addition to a reef tank and doesn’t stress other fish.
