The time it takes for goldfish eggs to hatch into fry mainly depends on the water temperature, usually ranging from 2 to 7 days.
The Influence of Water Temperature on the Hatching Time:
When the water temperature is maintained at 15-20℃, it takes 5 to 7 days for goldfish eggs to hatch into fry.
If the water temperature is raised to 20-22℃, the hatching time can be shortened to 3 to 4 days.
When the water temperature reaches around 25℃, the hatching time is only 2 to 3 days.
Other Influencing Factors:
Water Quality and Oxygen Content: Clean water quality and sufficient oxygen content are conducive to the normal development and hatching of fish eggs. If the water quality is polluted or the oxygen content is insufficient, it may lead to hatching failure.
Light and Carbon Dioxide Levels: Factors such as climate, light, carbon dioxide levels, and pH can also affect the hatching time. In particular, the water temperature and dissolved oxygen content are crucial for the normal hatching of fish eggs.
Precautions during the Hatching Process:
Control the Water Temperature: Use equipment such as a heating rod to keep the water temperature within the appropriate range.
Keep the Water Quality Clean: Regularly change the water to maintain the cleanliness and stability of the water quality.
Increase the Oxygen Content: Increase the oxygen content in the water by increasing the water flow, using an oxygenation device, etc.
