The sea hare arrived healthy and stayed active in my 55-gallon tank. It doesn’t eat much and blends well with the reef community. Only recommended for expert aquarists due to specific care needs.

It’s a beautiful addition to my tank. I’ve had it for three months and it’s still active and calm. I do need to monitor water parameters closely, as it’s an expert-level species.

Perfect for a reef setup. It’s peaceful and doesn’t cause any disturbances. I appreciate the clear size information provided. Only issue is it takes time to acclimate.
