Anemones will find a spot where they are happy with the light and flow. The problem is that it is not always where we would like to see them. If you are intent on moving simply reposition a powerhead towards it and it may move on its own. There is really no reason to target feed it as it will get most of its energy from light.
Some people are like slinkies...they serve no real purpose yet can still bring a smile to your face when you push them down the stairs!:p
Have a great day! Brian
