I recently purchased a new gig nem from the LFS. It's looked good during much of the day, then shriveled late in the day and at night has detached some. Tonight it is detached and upside down in the sand on the side of the tank. It is shriveled, but not completely deflated. So, do I place it in a new spot or let it move on its own? My only concern with leaving it is there is very little light in the area it's headed for. Thanks.
