They don't usually lay eggs in captivity, it's really hard to get them pregnant, too.

Goldfish are egg layers NOT live bearers.

The female lays the eggs in a cluster and the male fertilizes them by swimming over them and releasing sperm.

During breeding season, the male goldfish will develop tiny lumps behind the gills called tubercles. This signifies he is ready to fertilize eggs.

Female goldfish that are pregnant will have a very distended abdomen and will look very fat.

After a few days they will lay the eggs.

Once the eggs hatch the parents and other fish in the tank will not tend to the fry and in some cases will readily eat them, so they MUST to be separated from the young.
