I have a male peppered cory catfish that has been breeding with all my females. I watch the male chase the female if his choice, and they successfully breed. After the females places the eggs on the tank walls, I carefully remove them and place them in a well circulated container. After about two days the eggs show no signs of life and grow fungus. Is it possible to have A sterile male? If not, what could I be doing wrong?

    Hard to say what's going on, it could be possible the male is sterile. If the eggs are firm, then they are probably not dead. Fungus grows on dead eggs. The best fungicide for eggs is methalyne blue. Some people also add Red Cherry shrimp to help keep things clean in the grow out tank. Also to help prevent its growth make sure the tank water isn't stagnant (has adequate aeration).

    I know my tank is clean and the water temp. Is ware it should be and the PH levels are also correct. I have a standard filter outside the tank, with oxygen, and I also have a slow but constant currant in the tank. My Corey's are happy and healthy enough to breed constantly. Every other day I wake up to multiple egg clusters all over the tank. But after 2 days they stay that white clear color, from what I've read means there not fertile and then the fungus grows:/...

    Water conditions will do that sometimes.  I would do an amonia test.

    My corys are a lot more active mid tank now. One of them has turned bluish and spends time with his mouth near the surface in the back corner. The other one entices it away to play but I think the blue one is slowly dying. I think the blue is from low oxygen. This has been going on for several weeks now. There is lots of oxygen in the tank from 2 filters and a power head too. Have yours changed color?

    You may have a high PH level.
