Pond snail problem!!

[eemmais]

My tank has pond snails :/ Not too many, maybe around 20 snails. How can I get rid of them?? Thanks

Put a piece of lettuce in there, when they're on it eating, remove the lettuce with them on it, you may have to do it more than once & I hear doing it at night works best. OR get an assassin snail.
