I now too am infested with snales. They hitched a ride with some live plants I bought. Thankfully they are only in my 10g med tank that isn't occupied right now. After a recent med-tank visit from one of my big goldies the tank did get rather messy. I was intending on cleaning the tank once I came back from my weekend but they sucked the glass sparkeling clean so I'm rather on the fence about what to do with them.
I'm quite sure that if I don't make up my mind soon they'll only get worse and worse...
Snails are fine to keep. They are just a pain if you intend to keep live plants. Also, if they over populate your tank, there might be some problems with ammonia levels. If you want to keep them in check, just buy one or two loaches. The loaches will eat the snails, but if there are only one or 2, they won't totally eradicate the snails.
