I have a seriously question about growing Corydoras Frys that I don't really understand. I've been bred some Corydoras Caudimaculatus and Corydoras Sterbai for almost half year, but I still cannot get them growing up completely successful. And I've been tried the best way to get them growing up completely, but it still doesn't work on me. But, I won't give up for sure, and I will solve my problems again and again. But, I find out one new thing that I don't understand WHY!!!, but I hope that someone can help me to answer this problem.
After I could hatch some of my Corydoras Caudimaculatus and Sterbai Fries, I have been seperated them in my 10 gallons tank with a big Sponge Filter and a strong air pump. And, I always feed them with Tetra Colorbits and Color Spectrum Thera+A. I change the 40% water every two days, but my Corydoras Fries still keep dying little by little, but almost every single day.
On the other hand, I have some Corydoras Fries in my Breeding tank as well that I didn't take them all out because sometimes when I've been picked up the eggs, and some eggs will drop down to the bottom of the tank and hard to pick them up, so I left them like that, and all eggs were hatched. And, all these Fries from the breeding tank grow up and never die that make me wonder WHY!!! Because my Breeding tank looks MORE DIRTY than my seperated tank that I grow up all my Corydoras Fries, and I change the water much lesser than my Fries tank, and I always never change for a week sometimes more, but all Fries in the Breeding tank never die. But, the Fries tank that I seperate I've cleaned and changed the water every two days, but Fries still keep dying. That's WHY I don't understand. Can someone help me figure out. It will be greatly appreciated.
