Tonight I looked in my 6 gallon tank with my 1 male guppy in it. I SAW A TINY SNAIL! I was wondering HOW in the world that it got in there. A few weeks ago I got 2 live plants to put in there but then transferred them to my 29 instead. When I got my plants I could see no snails in the tank where all of the live plants are kept. I think it's really weird!
