snails

We have these two snails in our fishtank now and they are getting bigger. I not entirely certain if it is just my imagination or not, but the fish are looking smaller and smaller compared to them. This evening, after my all day headache finally subsided, I got my software and hardware all to finally jive and I shot some time laps of one snail (he's not moved since this video, when they go they really go, when they stop, they really stop). The video is only a couple seconds and silent, more another time.
