This is a hard one, I'm having trouble getting a clear shot with my camera when he is around. Looks kind of like a snail, but its shell appears soft. This guy started off really small and now is about 1" long. Not sure where he came from either. heh.
He also emitted a bunch of white stuff when I just approached the tank. A small little cloud and then it dissolved away.
