snail

This is a Collonista snail. It's a little hitchhiker, and doesn't grow to be bigger than a bb. Usually you'll see them late at night coming up the glass as tiny round dots. Great little grazers. In one of these two pictures, you'll see an astrea in the shot for a size comparison. This little guy was actually bigger than most. I do feed a lot. lol
