The rabbitfish looks beautiful in my 100-gallon tank. It’s peaceful and doesn’t bother the other fish. I’ve noticed it occasionally nibbles on a few soft corals, so I’ve moved them away. Overall, a good addition to a reef tank with proper setup.

Arrived quickly and the fish is active and healthy. I’ve kept it in a mixed reef tank with hard corals. It doesn’t eat much and seems to be adjusting well. Just keep an eye on soft corals near the tank walls.

This fish is calm and fits well in my tank. I appreciate the clear size information. It’s a great choice for intermediate reef keepers who want a colorful, non-aggressive species.
