Night of the living dead (fish)

After the Swimmy Hokie episode, Jason took Katie to get a new fish. They came back with three mollies. One disappeared shortly upon return home (about 2 months ago), one died, and we've managed to keep the third alive. Kerinda (my sister) brought about a million baby snails to add in with Gary the Snail (who is now the size of a Mack truck), and nothing else exciting has happened. Until this morning. I fed them, when this strange looking corpse came to the top. A greyish-white, very-dead-looking fish. Yet he ate. He was... ALIVE. Then he floated back to the bottom. He's still in there, still "breathing". Let me remind you, we have a 5 gallon bowl. There's no where to hide.

Amanda (an avid fan of the living dead), you may be right - the zombie invasion is imminent. It's apparantly begun in my daughter's room.
