I agree with the others. Your clown may never move into the anemone, there is nothing you can do but wait and see.
I have multiple anemones, have had them for years and never feed them. I used to but find it unnecessary and sometimes causes more stress than it does good.
Location is gonna depend on the anemone and where it feels most comfortable. A newly introduced anemone may go into hiding for a few days, then wander for a few days finding the perfect flow and light to suit it's needs. It may end up in a spot that is totally out of view for you but moving it would only stress it and may compromise the health of the animal.
Be sure to keep your water quality good and be patient, and maybe you'll be rewarded. Good luck.
