Default Discus breeding fertility drop

A few month ago when i first got my discus pair to breed, 90+% of the eggs managed to hatched. Nowadays, only 10% of the egg are fertile with 90% becoming white. Anyone know whats happening to my discus?

Could be water parameter problem. What's your WC regime and water parameters?

Try to see if it helps by using meth blue.

If it doesn't helps maybe its your water condition.

I have never check on water parameter as I normally do 100% water change at least once a week. Normally I can see them laying eggs one or two days after the water change. If they don't lay egg, I do another major water change within that same week itself. Can advise me how water parameter affect the fertility?

Btw for meth blue, is it to prevent fungus or is there another reason for using it? My female discus is very hardworking when tending the eggs and I didn't see any fungus developing until a day or two after the fertile egg have hatched.

How about your water hardness parameters? To me, best to be around 6.5 and water aeration is also important.

It may be the male. But water and may other factors affects whether the eggs hatch too. Many factors...
