of goldfish is closely related to the water temperature. If the water temperature is 15-20 degrees, the incubation time of goldfish is generally 5-7 days. If the water temperature is 20-22 degrees, it will take about 3-4 days. If the water temperature is 25 degrees, it only takes 2-3 days to hatch.
