If the anenome is shriveling up when the lights come on and moving to a low light location, your lights are too strong for it right now. It may take some time for it to get used to them, or it may never like that much light. Wherever it is located now, I would put about 3 layers of egg crate or something else to dim the lights above it.
As for it not eating in its first week, I would leave it alone until it it quits shriveling up. I typically wouldn't feed an anemone during the first week, and a lot of people have healthy anemones that they never directly feed. My anemone in my RSM130 hasn't been fed in over a year and still doing great.
Your clowns may never take to that type of anemone. Occelaris clownfish like Gigantea's and Magnificent's in the wild, so that is your best bet to get them to take to an anemone. With that said, those are 2 of the most difficult anemones to keep alive. The picture trick I have heard will sometimes work, but your clownfish may never take to the anemone. I had an occelaris pair that were in a tank for a year with an anemone and I tried every trick I could find and they wouldn't go anywhere near it.
If you want a type of clownfish that is supposed to go in almost any anemone and usually go in one quickly, get a pair of clarki's.
