hatching temperature for goldfish eggs? The best hatching temperature for goldfish eggs is 18 ℃. Because the appropriate temperature can make the goldfish eggs hatched the healthiest young fish, because the temperature can not only affect the hatching time of the eggs. When the temperature is higher than 18 degrees Celsius, it takes only two days for the eggs to hatch. When the temperature is lower than 18 ℃, the time is about a week. Studies have shown that when the temperature reaches 18 C, the young fish hatched from goldfish eggs are the healthiest. Because of this, their constitution is stronger, which can reduce the risk of disease in the future.
the fish tank when goldfish spawns? When spawning, we need to create favorable conditions artificially. This will increase their chances of fertilization. First of all, we should control the water temperature and try to keep the temperature at about 20 degrees Celsius. Experiments have shown that this temperature is the most suitable for spawning. Then, before spawning, the water quality should be kept clean and the water in the fish tank should be changed. This can avoid cross infection.
Secondly, a layer of translucent cloth should be placed on the outside of the fish tank, which can reduce the sunshine and create a quieter environment. They are more likely to lay eggs only if they feel undisturbed. Finally, increase the amount of dissolved oxygen in the fish tank, which can promote ovulation. After spawning, the parent fish should be taken out in time for rest.
