Our tank's biology up close

I got really excited for a few minutes. I thought this was a coccolithophore.
I think it's actually a radiolarian. Awesome anyway.

...though the poster of the video is using some new math to count to ten.

Alright, finally getting around to posting these pics and vids. This past weekend I took a quick swipe of my aquarium glass before I cleaned it off. As with all the others posted full resolution on flickr.

This is fascinating! I could look at this all day, what a great idea
 
Video playlist. Most all vids support at least hd, 4k, and many higher resolutions. Some are neet to see at .25 or .5x speed. One of my favorite things to watch this time were the dark field ciliates processing lots of water. Have to go full screen and you can see the currents flowing by.

Had to take a break from work.

Going 3" into a 5-6" area of my sand bed.
