I have no idea why, but one of my clams decided to up and die today. The other clam, which was about 8 inches away, is doing perfectly fine and normal. I came home, and the clam was covered in snails. I pulled all the snails off and moved it up on a rock, but it was all retracted and the flesh was turning red. I flipped it over, and its foot was rotten and slimy and stringy. Yep, that was the end of it. Any ideas??? I'd had it for about two weeks now.
