Is it bad to use chemicals to get rid of snails... from what I've read, it is risky for the fish. I haven't seen very many snails around the tank, so I think that my betta may be eating them. But, I know that in a few weeks I'll see a bazillion babies around! So will the chemicals hurt my betta? I've already tried using food as bait, picking them out by hand, feeding them to my betta and totally tearing down the tank, but they still are taking over the tank!!! How do I keep them under control without having to use the chemicals?*crazysmil
