The Domino Damselfish arrived healthy and active. It quickly adapted to the tank and started exploring the rock formations. The white spots developed well over the first few weeks. Great for a reef setup with some structure.

I was impressed by how territorial the fish became once it settled in. It stayed near the rocks and didn’t seem stressed. Feeding it marine flakes and frozen foods worked well. A bit shy at first but became more confident.

The color change from juvenile to adult was noticeable. The white spots spread nicely over time. It’s a beautiful addition to a small reef tank with proper hiding spots.
