Love it! Music is a great fit to the scene as well.

Did you use cover slip? What objective magnification was used?

Thank you for sharing!

Hi there Johann,
This is great. Amazing video!
Thanks for sharing

Thanks guys, appreciate the feedback

Zzffnn, I filmed it in a petri dish using a stereo microscope.
I first tried filming it directly in the fish tank - but that didnt turn out well:

Wow! Who would have thought that possible?

How long did it take in actual time?

Thanks for sharing!

Outstanding video !

The music is very dramatic and perfectly suited to the action.

It is video for Nikon Small World in Motion contest

Zzffnn, I was zooming in and out while filming, so didnt really take note of the magnification - I would say about 10x minimum and 80-90x maximum zoom. Hope that helps

Fantastic work! This can be broadcast on National Geographic just as it is. Well done!
