N. guentheri eggs
I've got 3 packages of S.Am. annual eggs from the same seller which need a couple of weeks yet before being wet but I'm off to see if there are actually eggs in those packages before I continue storing and then wetting them.
4 eggs of Simpsonichthys santanae have hatched out of 15.
Anything yet Robert??

I am sitting here feeling what I think a father would be feeling awaiting the birth of his first born
I initially put the N. guentheri eggs into water at 15c. They had actually been in the water for 4 days before they started to hatch. You might have to wait the same length of time.
With the S. santanae I took some RO water and put it in the container and dropped an ice cube in to bring the temperature down to 10c. The first 4 of those hatched after about 4 hrs, I've left the container to climb on it's own to room temperature and and a few more have hatched today. Róisín's container has had two or three more hatch today so I'm going to leave them in the water until tomorrow.
What did surprise me was how tiny the N. guentheri are, I expected them to be slightly larger than the S. santanae but they are actually about 2 thirds of the size and with the peat background extremely difficult to see. I, very, very gently, used a spoon to ease the peat away from one end so that there is a clear section of the white container with very little peat on it and it makes them much easier to see.
I don't think you will have problems, it'll just take a little time, especially with warmer water. Those initial rains in nature are of a much lower temperature than the ground the eggs are in.
Keeping fingers crossed for you.
As Bill mentioned , The fry could be lying on the peat and it would be hard to find them.
Their size is also why you have the debris from your pond prepared in advance as to have a food source in the form of insufuria small enough for them take.
Don't forget, these fry are really going to try out your eyesight something wickedly as well
First of many I hope Robert.

As Bill mentioned they are tiny so there might be another few in there.
Hatching would be normally very rapid (within 40 to 60 minutes after wetting) if a first wetting was sufficient.
I also would use aged water that had had fish in it (but not adult killifish though)

Bar joining the BKA has any one any good source for killifish eggs going to give it a week let the microworms take hold then try hatch some more.
at the end of the day it becomes nite

I'm always wary of feeding any newly-hatched fish with anything other than infusoria, I'm not saying that's why you lost them, but that's how I always did it. So far ours are still alive and will go onto microworm later this week.
I'll second Eric, dry off the peat and incubate again for a couple of weeks.
