Ahhh bta's will pick their space and there is nothing we can do to change their mind. Anemones are like small children.....they do what they want. As long as it is getting light and you can feed it I would leave it where it is. I tried 14k halides and I thought they were too blue so went back to the 10ks. I might try a different brand bulb and see if it makes a difference.
