The pictures are really nice. I would look to see if there is a reason to see why the anemone chose that location. It may be that your lighting is a little more intense then the lighting from the aquarium that it came from. It could be something to do with water flow also. Might be that there is less water flow there then in the front of the rock, or maybe more then in the front of the aquarium. Not sure what lighting that they have in those aquariums, so it may take a while for it to get used to your lighting.
