. Normal goldfish can spawn after feeding for about a year. Because of regional and temperature factors, the spawning season is usually in spring and autumn every year, when the temperature reaches about 16-20 degrees. Most of them lay eggs in the early morning after rainy or foggy days, about after 5 o'clock. If the male keeps chasing the female or even knocks her over, it means that they will spawn soon. Before spawning, aquatic plants should be put into the fish tank, because the eggs laid by goldfish need to be attached to the aquatic plants before they can be taken out. You can also change some new water appropriately, and the friction of the water flow on the fish body can promote the spawning of goldfish.
should goldfish pay attention to after spawning? Goldfish need to separate the mother fish from the eggs as soon as possible after spawning, because the mother fish may eat the eggs over time. It's better to find a new container and put the fish eggs in it after disinfection. Do not change the water or stir it, otherwise it will affect the development of fish eggs. An oxygenation device should be installed in the cylinder, and the water temperature should be controlled at 20 degrees. In about 3-5 days, small fish can be hatched. Small fish do not need to be fed within three days of hatching, and the nutrients in the mother's body are enough for them to absorb. Three days later, after the small fish have the action of foraging, they can start feeding.
