My New Rock Flower Anemone

Just added this rock flower anemone. I placed it in a crevice on top of the rock but within 45 minutes it moved down to the side of the rock and has hunkered down. At least he/she (I've read they reproduce sexually) placed itself in front of the tank so hopefully it will stay put. My mushroom isn't happy with its new neighbor as you can tell it doesn't like touching it. I was thinking of moving the shroom but I'm interested to see if it will move away on it's own over time possibly leaving behind part of its foot and sprouting more. Video of my new tank here.
