When I first looked at them they all seemed viable and then three days later (I work the entire time the lights are on Saturday and Sunday) on Monday 7 of them were milky white or gone. The shells were gone on a few of them like in this pic.
The male will eat those in his cleaning and caring for the viable eggs. I have seen him mouthing the eggs periodically, and i think a few empty cases were there. They spawn so often now I scarcely bother, as I have saved some from other spawns and now I don't know what to do with them. I gave some to a local fish store. Not everyone wants these, they do slightly damage fine-leaf plants (my pygmy chain swords). I have the grown fry in tanks with Java Fern, they can't damage that plant. I've found it very easy to train the fry to graze Omega One Veggie Rounds.
