It is worth leaving the fry in with the parents the first couple of spawns as there is a high rate of healthier fry. I did a test and the fry that I left with the parents for 3 days were MUCH healthier than the ones that were in the tank by themselves.
I don't really know what this "nipping" is but my angelfish do it to. If I were to guess what it ment I would say that it was the male showing to the female that he is ready to breed... but I'm not sure.
You can't be absolutly sure what the gender of an angelfish is until they are breeding. the females egg tube will be thicker, and the males will be piontier. when they have them out when breeding, it is very easy to tell the difference.
I would recomend feeding Rotifera, hikary first bites and then after they have grown a bit finly crushed flake food.
