in a few centimeters. Goldfish can spawn in about 10 centimeters. Whether goldfish can lay eggs is determined by the development of reproductive system. Like those goldfish that develop faster, they can lay eggs when they are about 8 centimeters long. The number of eggs laid by goldfish has a great relationship with the size of goldfish. Large goldfish lay more eggs. Like those strong, long goldfish, they can lay up to a thousand eggs at a time.
goldfish before spawning 1. Disinfection: Before moving goldfish into the fish tank, the fish tank should be disinfected and washed with salt boiled water or potassium permanganate solution, and then filled with new water after soaking. To control the water temperature of the new water, it is better to raise the water temperature to about 28 degrees Celsius, and the water temperature must not fluctuate greatly.
2. Check: Be diligent in checking before spawning, and solve problems found in time. For example, if the male fish is weak or the number is small, it is necessary to replace or increase the male fish in time.
3. Feeding: Before spawning, the goldfish's appetite will decrease. At this time, it is appropriate to feed a small amount of food. It is best to feed live bait. Live bait can promote the full development of goldfish gonads, improve the quality of eggs, and improve the fertilization rate and hatching rate. Be sure to clean and disinfect several times before feeding live baits.
