Added the Blue Spotted Rabbitfish to my 55-gallon reef tank last month. It’s very active and constantly grazing on algae. The blue spots stand out beautifully against its olive body. It’s peaceful and doesn’t bother corals or other fish. A great addition for both looks and function.

This rabbitfish has become a highlight in my tank. The color pattern is vibrant and unique. It’s calm and doesn’t compete with other fish. I appreciate how it helps keep algae under control without needing extra cleaning.

The fish arrived healthy and settled in quickly. The blue spots are very noticeable. It’s not aggressive and stays near the algae-covered rocks. A bit shy at first but now it’s active and eating regularly.
