When I bought some plants at a local fish store, I noticed a few snails would unexpectedly pop up. It isn't a real problem and they've disappeared I believe, but my question is: how do I prevent unwanted snails from aquarium plants (if there are any). is it possible to quarantine the plants? rinse them really good before adding to your tank? I just don't want an invasion of unwanted snails as I've read on these forums previously. Thanks!
