PS. Sorry about the image quality. All I have is an iPhone that I try my best to hold in place. All were taken at 640x
1. Very green and stationary. They seemed separate but clumped up together.

2. A few large clear motionless structures

3. I followed a few of these little things around for some time. It's kinda hard to make out in the gif but they were quiet fast and roughly cylindrical with a little black spot in the rear half. There seemed to be a definite 'front' which it's would direct it's jerking or circular movements.

4. Final silly question. I tried staining a drop with Methylene blue. Not really sure what I was trying to accomplish but I only just bought the stuff so I was excited and wanted to see what would happen.

I figure this is either the water and methylene mixing in an odd pattern or perhaps oils from the fish food. Anyway my question - is there any reason to stain a water sample like this with Methylene blue? What can I use it for besides cheek swabs?
