Peabody's paradise has mystery snails. Beware tho I started with a few eggs on a plant and now there are hundreds. I have smush snail days 3 or 4 times a week and 2 assassin snails still there are hundreds. 1 is pretty big tho he's about an inch and good looking. My lace cat loves them but he's in the spare tank and the snails are in the main tank.
