Thats awesome, I have been a Fish keeper for almost 45 years now. I currently have four Aquariums set up. Snails can become very invasive. If you have one in a plant you probably have hundreds you can't see yet. Its always a good idea to rinse new Plants under running water before you add them to your tank, gets rid of some of the Snail eggs. If they get out of hand ( clog Filters and such) just add a Clown Loach fish or Assassin Snail to your tank, They make quick work of unwanted snails. Good luck with your Tank, it should bring you years of enjoyment.
