Small snails appeared - good or bad?

[Shadowfax]

Hi, in my 45 gallon tank (180L) I have noticed some small snails appearing, are these a good thing or bad thing to have? If bad how can I get rid of them?

Thanks

S

they clean your tank and look cool. But if you want to get rid of them try the lettuce trick.
