help with anemone

[reefnut]

well its my first one and im 99% sure its a condy, it was cheap and looks the same.My problem is that ive now had it for about 5 days and he has been moving around my tank alot.Yesterday morning he found a spot that he apparently likes(hes been there for 24 hours)but it is in the darkest corner of my aquarium.I came home from work today and hes shrivelled to 1/3 his size and turned a greenish gray color.So I think he will be a goner for sure.My tank is a 33 gallon with one domino damsel,1 blue green chromis,1 emerald crab,one peppermint shrimp and a large turbo snail.There is a 3 inch lsb and about 25 lbs of lr.Levels are all good and the lighting is power compacts.Any comments or suggestions would help.

Thanks.
