So my snowoynx had laid a nice clutch of eggs last Saturday evening. Starting last Friday morning I could see the silver eyes. I started that night by turning off pumps for over 2 hrs to try and collect the fry, none hatched. Saturday morning looked like some had hatched there were not as many silver eyes as the previous morning. So again I tried turning off pumps for over 2 hrs shined my light in corner of the tank and nothing again. And pretty much the same for Sunday night. This morning I can still ser a handful of eggs with silver eyes, everything else is gone. What is going on why aren't they hatching? Am I not leaving light off long enough? Are they not hatching and dying before they do?
