Well, I was out on the Mississippi the other day fishing, and I brought in a bunch of plants and weeds. I kept some samples and put them in an unfiltered tank with a light overtop and sand substrate. I was looking at them recently and I came across a strange snail. It looks like half of a clam shell and it moves VERY slowly across the glass. I was just wondering if anyone has any idea what it is. I can't get any pictures, because it's only about a milimeter across. Thanks!
