I have had Corydoras caudimaculatus for 40 years or more. I had spawnings on many occasions but could never get a hatch. A few years ago I started getting a small hatch but the fry would always die soon after hatching. Last year I finally raised 2. That was the turning point as they grew into young fertile males. This year I succeeded in raising 9 that are now an inch long. This was done in an act of desperation when I moved dying fry from a bowl into the fry saver with some King Tiger fry. From then on the dying stopped and they thrived and grew quickly. They are now in the tank with my King Tiger breeders and doing just fine. At the moment I have another spawning of about 20 just hatched in a bowl and as soon as I get their water changed over to that of the Tiger tank they are going in there in the fry saver.
Never give up on a quest. You can only learn from your failures.

Do you think it is just that they need the shallow water of the fry saver?

I had some experience with Panda or Albino Cory hatch for few weeks. Whenever water changed with cold tap water, next day, always have some eggs appear in the glass around 30 eggs.
First patch, I took all the eggs to the breeder box without airstone, next day they turned to dark brown with fungus. Failed first time.
Second patch, I saw some eggs with black thing moving. Then I moved them in the breeder box, next day, all disappeared. Failed again.
Third patch, Same thing happen, but I put them in the breeder box without holes. Finally, next day morning 10 of the fry. So happy to see them.
Then I had set up a 1-2 gal setup for them now. But what should I feed them now? I try Hikari sinking wafers, but they seen not eating it.

I think that as soon as you start to feed them the nitrates rise. They need the water flow and continuous change from the staple water conditions in a large tank.

I take the eggs and move them to a bowl. I add a drop of acriflavine or methylene blue and put in an air stone. When they hatch in 4 to 5 days I change half of the water. In another 3 days the yolk sac is gone and they are ready to start eating micro worms after nearly a week they should be fed baby brine shrimp or golden pearls. I would not advise putting them in a fry saver before they are ready to eat. During my time in the hobby I have raised at least a few thousand.

Thank you for your advice.

Knowledge through experience is a powerful thing. Congratulation Charlie on being able to produce more fry alive.
