I have been trying to film an Oryzias Latipes egg hatching for about a week or so now. I removed the eggs from some moss in my tank with a pipette and placed them in a deli cup with tap water and whatever water was in the pipette. The first few days I only saw a few things darting around in the drop of water on the slide with the egg.
After a week I noticed all sorts of things alive and moving, some even attached themselves to the egg. I'm no expert on what any of these things are, but I imagine that the small things are paramecium. I can recognize that there are vorticella and a nematode, but I have no idea what the grabby big mouth worm thing is. Any insights?
I have been unsuccessful so far in filming the moment of hatching. I found myself watching all the little things that I never knew were there more intently and with more curiosity than watching the egg itself. Just thought I would share.
