I was just looking at my snail's bumming around the tank a minute ago, When something struck me. One of my bigger snail's looked a bit "Empty" I took him out and sure enough my eye's were not playing tricks on me. He's gone! Nothing left in his shell.
Does anyone possibly know what could of happened to him? Where did the rest of his body go? I feel so bad for him. They were all fine yesterday. I saw all 5 of them last night.
