Do you have to remove a pregnant goldfish from the tank baby fish live?

No, you do not have to remove a pregnant goldfish from the tank for the babies to survive. Goldfish are egg-layers, and the eggs will usually hatch within a few days of being laid. The fry (baby fish) will be very small and will need to be fed specialized food for the first few weeks of their lives. They will also need a heater and a filter in their tank to ensure that the water is at the correct temperature and pH level.

If you do not want the goldfish to breed, you can separate the male and female fish during the breeding season, which is typically in the spring and summer. You can also add plants to the tank, as these will provide cover for the fry and make it more difficult for the adults to eat them.
