I think it's just a pond snail, but would like confirmation from you more experienced people. It was maybe right about a centimeter long (maybe a little less), and I saw it just after I saw a little clutch of eggs stuck to the glass down by the substrate. I know I got a few hitchhikers with some java moss I got a month ago, but this is the biggest one that I've seen yet.
