You can get 50lbs. of cured LR on ebay for around $150 and that includes the shipping. I'm an ebay fanatic and I bought 70lbs. of really nice base rock for $99 and that included shipping. Take a look.
I also have an anemone that practically shrivels up to nothing just to open back up in a day or two. I've noticed that after it shrivels up it moves and then opens up 5 or 6 inches somewhere else. He may just be trying to find a happy home.
