How do goldfish reproduce?

Goldfish are found in many friends' homes and are specially farmed in fish tanks or large glass tanks. So how do goldfish reproduce? Let's have a look together!

First, how do goldfish reproduce

Goldfish reproduce by spawning and fertilization. Usually in spring every year, the temperature reaches more than 16 degrees, but it is better to lay eggs at about 20 degrees.

2. Main points of goldfish mating

1. Every breeding season, male goldfish will chase female fish, at first, only occasionally, then the chase behavior will become more and more frequent, which is the courtship behavior of male fish.

2. The mature female will release sexual information before ovulation to induce the male to step up the chase. At this time, the male will chase the female, hit the female's abdomen with his head and hit the female with his body, indicating that the male is ready to excrete semen at any time.

3. When the male fish chases the female fish all the time, and sometimes even knocks the female over, it means that they will spawn soon.

4. When the female sets its tail in front to lay eggs, the male will then ejaculate, thus fertilizing the eggs.

5. The fertilized eggs can produce young goldfish after about a week of hatching.
