The developed eggs will be primarily black and you should be able to see the fish's eyes and body.
Normally you put the date they were laid not an estimated hatch date. Contact the supplier and see what that date means. And ask them for directions about hatching the eggs.
I'm assuming they are Nothobranchius killifish eggs?
Thanks. Will do.
They're Aphyosemion Australe.
