I have a small anemone that hitchhiked on a piece of rock. It is about 3/4 inches across when fully deployed, has a bright pink center and clear tentacles with white dots on the ends. I'm pretty sure it is a strawberry. Recently I have noticed about 4-5 tiny clones groups around it. It happens to share the same rock as my xenia tree and I am wondering if I should be worried about it spreading?
