Corydora Eggs

[Paul_Obermiller]

I finally bred my Bronze Cories (yes I know boring old "normal" cories), some are partly white while others are clear. I put them in a Specimen container so they wouldn't be eaten. Should I hook up a air pump and let the eggs be bubbled? Is the white fertilized and the clear unfirt? Fill me in on how to raise them and everything! I am super excited. My Kh is 80, Gh 60 and pH is 7.0.

I don't know how to share pictures but if I figure it out I will add them.

Dan's fish room has a YouTube video out on raising corys. The white eggs are typically infertile but in his video he'd separated them out and to his surprise, at least one hatched. So, don't give up on them. He moved his eggs to a separate container and added five drops of hydrogen peroxide to the water and did frequent water changes. Some people use methylene blue to help the eggs.  Cory eggs are pretty tough and at least some should survive anything you do to them. I always like to add air to keep the water circulating, but others don't.

Thanks @gardenman, I am going to leave all together as it doesn't matter to me if they all hatch or not. If I add air it should just be a light bubbling nothing strong?

Yeah, gentle is better. You just want water movement over and around the eggs.
