Last night I was able to see my snail come out again, when the aquarium lights were out.
I have other names, maybe Honey, Owl, or Turny (ie) because he comes out at night/when it's darker.
Turny would fit too because he likes turning his shell around while sleeping during the day.
But it was a little comical (though not because I was worried), how I caught Autumn acting around him. She kept going close to him and flaring at him, then she would take the food I was trying to feed him, acting like everything belonged to her and NOT him. Seriously. She swam over and smacked his shell when she caught him moving around the tank. And then the snail took to being very sneaky to get around, only moving quickly while she wasn't looking and moving very slowly when she was so it wasn't noticable he was moving at all.
I had to stay up and watch to make sure he got food, lol
I can't get a picture up at the moment, maybe it will work later...>_<
