How do I get my BTanemone off of the rock it is attached to? I purchased it when it was about 6 inches in diameter. Not is has at least doubled it and is laying over my mushrooms, and button polyps. I think it is attached to the very same rock as the polyps, so if I do something to the anemone it has to be safe for soft coral. I am going to take it off and try to sell it. Thanks
