I just picked up two small banana plants at a local pet store. I'm a little paranoid about snail hitchhikers. I didn't see snails in the tank I got the plants out of, but saw them in other plant tanks in the store. A guy at a different pet store suggested dipping in a citric acid solution. Just looking for a second opinion. I'm trying to decide whether to try to citric acid or go with a quick bleach dip. Thoughts?
