Snails are pretty cool but they do tend to have lots of babies. you also might want to check out this link http://www.liveaquaria.com/product/scateg.cfm?siteid=21&pCatId=1075
They have some really unique stuff from freshwater lobsters (too expensive for me) to all kinds of shrimp (Ghosts are very cool, i have 3) and i'm going to get a couple of freshwater clams from them too.
the only problem with that site is that they are a bit more expensive than the local pet store. i would only advise getting something rare from them that you can't find at your pet store.
