The chance of eggs surviving is very small, the chance of fry surviving is even lower.
Most fish are either carnivores, or omnivores so by nature they will eat any fish that will fit in their mouth, even perfectly peaceful community fish. Angels are pretty good in that they take care of their eggs, while most other fish will eat their own eggs. However, those eggs, and any fry that hatch, will be live food for everything else in the tank.
Angels, if threatened, are also known to eat their own eggs to prevent anyone else from getting them.
Nature being nature though, there is always the chance of someone surviving, but I wouldn't count on it.
