Which kind of snails do you have, skimmy?. They're not always a bad thing.
I agree with this. Even the dreaded tadpole snails won't necessarily do any harm; the biggest ones in my tank are over an inch long and aren't hurting the plants at all.
Kribensis is a small, friendly (except when breeding) cichlid that will exterminate a pond snail population. They will eat small snails whole, and are expert at sucking out bigger snails out of their shells. They're unable to do anything about trumpet snails though, because these have harder shells and the shells have a protective lid they can close when disturbed.
