He said they hatched (got tails) so thats not the case.
Angel fry are difficult--they need warm, aerated, clean, soft water and extremely small first food. They are also the favorite snack of most fish in aquariums (including the parents). In nature, or a really large natural type aqurium they get the food from organisms in the water, or plants and clean water from upstream. In the aquarium you need newly hatched baby brine and/or microworms and you need lots of water changes. You can't just cut off the pump, try putting a sponge across the overflow, but if the parents are doing their job, they'll keep the fry in the tank. If you keep the parents in with the fry, they will also herd them to the food. If you remove the parents, the fry will have a hard time finding food and may get fungus from the lack of parental care. If your parents always eat the fry, you can try making them feel more secure by leaving the lights on, covering the sides of the tank or removing other fish. Or you can try removing one parent or the other, sometimes only one will be the culprit. If all this fails and you will do anything to get fry, then its time to remove the fry from the tank. Once they start wiggling, siphon some out into a pitcher and transfer them to a small tank or jar (1 gallon or 2.5 max). Read instructions on artifically raising fry. Don't feed until the egg sacs are gone and they are swimming, not wiggling. Keep the water extremely clean and good luck.
If you leave the fry alone in the big tank they won't find food and starve to death. If you are lucky they will find food in the little tank and grow big enough to dump into a five and then a ten and so on. If your tap water is hard, you may never have succuss, no matter what you do.
For the goldfish, search "swim bladder". Fancy goldfish seem succeptible to this sort of thing.
