Anybody have experience with these? I have eggs that appear fine, but still no hatch after 5 months. That seems like the long end for Hypsolebias (I worked with flammeus about 25 years ago and I don't remember that long a diapause).
The image is a microscope shot of one of the eggs.

you are more patient than I am!!!

I got fed-up waiting for my coamazonicus and wet the peat... I will rewet in 3 to 6 weeks in the hope that the wetting and redrying has stimulated some development.
