Its hard to say but i would say that eventually they most likely will.
With some cichlids it takes them a few tries before they get it right and stop eating them. Cichlids will eat the eggs when they feel that something is not right and or are stressed. Theres multiple reasons to why they would eat the eggs.
Angels can take more then a couple spawns to get it right. If you want to have angel fry for sure the best thing to do would be to remove the eggs from the parents and let them hatch and raise them in another tank alone. If not just let the parents keep trying, although to be honest I've heard many times that it can take a while.
Don't worry about the parents looking for the eggs or anything like that. The pair should remain and spawn again in the future. Another thing is make sure you actually have a pair. Often two female cichlids will lay eggs together not knowing the other is not a male. The eggs then will become white and fungus. Any eggs that fungus usually get eaten. Did the eggs turn white at all?
Also just thought id say i meant baby brine shrimp is waht you should be feeding the fry. Sorry i just mentioned brine shrimp in the last post
Goodluck, I hope you have a pair and they spawn again. If my apistos do again and i can get the eggs out maybe we can trade some fish
