False alarm

Last night before I went to bed I went to check on Baby J as I always do. I went to look at the dead snail and make sure the other fish weren't nibbling on him. There he was, slithering away on the gravel all happy. What happened? He decided to go into hybernation? Is he a deep sleeper? He was dead, we would swear on it. Now I worry that the other one wasn't really dead and is probably crawling around my bathroom. One day I may hear a crunch during my trip to my midnight pee break.
