A few days ago a girl at my local fish store talked me into buying some hornwort. I took it home and stuck it in my 'cute but useless' hexagon tank that was sitting empty. Today I noticed what I thought was a couple of bugs swimming around in it. When I looked closer I noticed that the bugs are actually small, surprisingly quick snails. I tried to get a picture, but it's so small and quick, the pictures are terrible, but I thought this one may help give an idea of what I'm talking about. image Any ideas who this hitchhiker may be? Thanks guys!
