Hiding Rock Flower Anenome

[Lilly]

I have a rock flower anenome that has been "hiding" under a series of rocks towards the back of my aquarium. It has been there for the past week since we brought it and others home from Reefapalooza. It is not getting much light, but there is some. Will he be okay there? We can't feed and it seems to be getting covered in sand and detritus from our goby. All the others are out and are doing great.
Any advice?

I've had some of mine hide for days or weeks then emerge and are fine. I once had one emerge totally bleached from lack of light. I also had a couple that hid and died from lack of light.
