I recently moved, yes tank and all. Fortunately only about 200 ft. I did empty the tank, all but the LS and 10 gal SW. Everything went pretty well, I only lost my YT and Lawn Mover Blenny. Well the Leather shroom decided to take a nap. He(it) is about 12" dia. A week after the move the move, no polyps would extend. There was no drooping, cap would open up, just no polyp extension. I was looking for some slime or other clue indicating stress. Now he is open and all polyps are extended. Could it be getting ready to split or something?
