What is this?
Can anyone help me identify this thing? I’m sorry I can’t get a better picture, but it’s so small my camera is having trouble focusing. A snail of some kind? I don’t see a shell or anything... It’s just been hanging out on the glass, you can see it’s clearing a small trail of algae as it moves. If it’s some sort of parasite I’d love to be able to remove it before it disappears. Thanks!
