Glad to see the ooth hatched, I ordered one from Steve too. I had no idea they were incubated and ready to hatch, but if mine do soon I'm ready.
Congrats on the hatch, and don't worry - as Denise (Dmina) says, "it's suppose to be fun".
I can't wait to see some pictures, the ones available online are really lacking.
If you are having problems housing them all, you can use a large container to house them all together for now. Something like a old 10 gallon fish aquarium (must make a lid using microscreen or something), a large clean cheese ball container, or similar. As they are L1 you shouldn't have any problems with cannibalism yet, and is a easy solution for a large hatch. I would recommend you put in a inch or so layer of coconut fiber in the container to help hold humidity, soak it good then put in the nymphs.
Then in two days (Saturday) add in 2 Melanogaster fruit flies for every nymph, and mist them. During the meantime you can start getting some nymph cups made and ready for them. Or as I seen you are trying to sell them, you may just leave them as a community until you sell them off.
Best of luck with your nymphs.
