I would leave the eggs with the parents next time, especially as you are not rearing them for numbers.
First 3 times the parents may eat the fry or eggs if you bother them too much. But, they should be good after that.
By removing the fry at about 2 weeks old, you will prevent them starting to feed on the parents' slime coats, and you will have the parents do all the dirty work for you.
Alternatively look up how to make a gallon jar to keep the eggs and newborn fry in for next time....
You take a jar, cut a piece of foam large enough to fit tightly in the bottom of the jar, so that nothing can get stuck between it and the side of the jar, lift it about 1/2" from the bottom, Do the same for the neck of the jar. Make a small hole in the center of each foam sponge.
Insert a half inch PVC pipe through the holes in the sponge, but pull it back a little so thee is a gap between the bottom of the jar and the tube. Slide a piece of airline down the tube, but not all the way to the bottom opening.
Now when your air pump is running, bubbles will come up the PVC tube, pulling fresh water into the jar, circulating out be the tube's opening. Turn off airpump when feeding to keep BBS from being sucked into the bottom sponge.
Cut another slit in the top foam, you can stick a turkey baster through it to deliver small fry or eggs into the cavity. This is good for about 250 baby angelfish. The jar stays in the parental tank, so it is not subject to large parameter swings like in a tiny tank, plus you need no extra heaters.
I hope you have brine shrimp eggs. You might as well do a trial hatching just to get any wrinkles in your process ironed out. DO NOT FEED THEM UNTIL THEY ARE ALL FREE SWIMMING. One day they will still look pathetic, and just wriggle and bounce around, the next morning they are all swimming (their might be a few wrigglers or defective fry), but it should be such a small portion of them, that it doesn't matter. Feed small amounts and make sure all food gets consumed. You can add more small portions if they finish the first one.
Unless you keep them in a gallon jar in the main tank, do large water changes daily, trying to match temperature. When you do the water change, set out water for the next day's change, so that it can age a bit and gas off. A spare heater and air stone will be needed for this. They grow pretty rapidly and it is great fun. Its just pricey feeding them. Brine shrimp eggs are crazy expensive.
