Rock Flower Anemone, Ultra
The Rock Flower Anemone, also known as the Rock Anemone, is a member of the Phymanthidae family. Originating from the Caribbean, these anemones are found in a wide array of colors, with the oral disc often being a different color than the rest of the anemone. The oral disc lacks tentacles, and the tentacles are often beaded in appearance.
The Flower Anemone can live singly or in groups. They prefer to live on shaded, vertical rock walls, or within the substrate. They will bury most of their body in the sand, with only the oral disc and tentacles showing. These are fairly hardy anemones that will adapt to a wide variety of lighting conditions. These anemones tend not to wander about the aquarium and are a great addition to a reef aquarium.

Ryan Cameron –
Easy to keep and very colorful. I placed it on a shaded rock wall and it settled right in. The oral disc stands out nicely against the sand. It hasn’t moved at all after two months.
Victor Stewart –
Grew well in moderate lighting. It hides most of its body in the sand, which looks natural. Only one other anemone joined it, and they stayed together nicely.

Perfect for a reef setup. It’s hardy and doesn’t require much attention. The beaded tentacles are unique and add visual interest to the tank.
