I flipped over a rock in my refugium and found which looks like a oyster or regular saltwater clam attached to a rock. It is alive. I have noticed it opens a little, when I touch the rock it will close. Doesn't really look like a regular saltwater oyster to me but I don't think saltwater clams adhere to rocks??
