Is egg yolk good for goldfish?
If your fry are already free swimming, I suggest hard boiled egg yolk squeezed through cloth. Swirl it in the water as a mist. This will get some food into the fry but it should only be used as a temporary solution. Egg yolk tends to pollute the water quite quickly. Will goldfish eat eggs? Unfortunately, goldfish will eat their own eggs, so if you do want the baby goldfish to have a chance of hatching, you can't just leave the eggs in the main tank.
