Well, for sure you have a female. You should be able to tell the sex of the other one by the shape of the breeding tube, and of course, by whether the eggs turn out to be fertile.
I was breeding wild angelfish stock I caught in Peru years ago, and it was a totally different ballgame. Short version of a long story- good over beers sometime- is that the wild pairs demanded at least a 4-foot tank! Yikes! Crossed the wild females to black males; got some really nice fishes, but still very aggressive and territorial. Angels have been bred in captivity for decades, so this is a perfect example of how 'domesticated' and wild fishes can be very different. Anyone who has bred wild-caught Apistogramma will tell the same story. Here is a breeding pair of my F1's, and no, these are not 'veiltails,' it's how P. scalare look in the wild, i. e, 'wild-type' -

Good luck!
Not unusual for an inexperienced pair. Hopefully the white eggs are just ones that didn't get fertilized.Had to separate the pair as they were picking on each other pretty aggressively. I did notice a couple eggs turned white. I will update when I get home from work.
Have you put the pair back together yet? They usually spawn pretty quickly after a failed attempt, as you've seen already. No doubt the low temp was a stressor. Think ~85 degrees.
If you haven't raised angels before, you should be aware that the spawning bit is the easy part; it's raising the fry that is tricky. Whether you let the parents do this- which is one of the coolest things you'll ever see as the little ones sprout 'wings'- or do it artificially, the fry need scrupulously clean water. When I was raising angels I used completely bare tanks (no substrate) with just one piece of slate for the eggs, and a clean but well-seasoned sponge filter, and did 50-70% water changes every day. Even so, fry mortality is high for a cichlid. Good luck!
A direct current near the eggs works best...have a spare airstone to use?
