The midnight purple color is striking and the anemone is very active. It grabs food and moves around the sand bed. I’ve had it for three months and it’s still healthy. Just make sure to keep it alone or with strong, resilient fish.

Beautiful and unique. It’s not aggressive toward my larger fish, but it does chase small shrimp. I place it on the sand bed and it stays in one spot. Good for a reef tank with proper care.

Arrived quickly and looks exactly as described. The color is deep purple with subtle patterns. It’s active and shows interest in food. I’m happy with the purchase and will keep it in my 30-gallon tank.
