The midnight purple color is striking and the anemone is very active. It grabs food from the bottom and shows interesting behavior. I keep it in a 40-gallon tank with a mix of hard corals and fish. It’s aggressive but not overly so, and it’s a great visual addition.

Beautiful specimen with a unique purple hue. It’s active and responds to food. I noticed it sometimes touches nearby shrimp, so I’ve moved them farther away. Works well in low light and medium flow.

First time keeping a tube anemone and this one is impressive. The color is deep and the tentacles move naturally. It’s a bit aggressive, so I made sure to keep only hardy fish. Very satisfied with the appearance and behavior.
