Thanks, everyone. I saw my snail floating on top, tangled in the plants and I went to town with the camera.
Before anyone thinks I'm a great photographer, I'll have you know that I took 100+ shots. Only a third of them were any good and half of those are essentially duplicates.
I feel a bit ashamed of myself for taking that many photos of my tank. It's okay though. That's what AA is for, right? I just tell my girlfriend AA is Aquariums Anonymous, not these forums.
