How long does it take for goldfish eggs to hatch and how fast do they grow?

Goldfish eggs typically hatch within 4 to 7 days, depending on water temperature and conditions. After hatching, the fry will absorb their yolk sacs for about 3 to 7 days before they start swimming freely. Goldfish grow relatively quickly; they can reach about 1 to 2 inches in length within their first year, and with optimal care, they can continue to grow significantly larger over the following years.
