Weird thing in my nano tank???

[anirbas91]

I decided to check on my nano tank and I saw these weird clear blobs moving on the glass. I've never seen then before. I tried attaching a video but the file was to big. So I attached an image. Any idea what it could be?

The tank only has macro algae, live rock, and sexy shrimp.

The one in the middle might be a flat worm. Kind of hard to tell from the image. Did it move relatively fast across the glass?
