Infertile male?

[Hellfishguy]

I have a pair of Laetacara araguaiae that was born in November 2019. They spawn every week or so & formerly produced many young. Lately, however, all of the eggs turn white soon after spawning. Can this be remedied or is my male permanently infertile?

Has anything changed about your water lately?

Same conditions as always. I had the pair separated for a few weeks when they weren’t getting along, & after I removed the divider none of the eggs were viable.
