naturally? Of course, domestic goldfish can breed naturally, but if you want to breed domestic goldfish, you must first ensure that there are males and females of the right age in the tank. Generally, the male fish is more slender and the female fish is more rounded. The caudal peduncle is stout, the color is more bright, and the cloaca is long and narrow.
1. If you want goldfish to breed naturally, you should be extra careful in feeding at ordinary times, and pay attention to the nutritional balance of feed. The healthier the goldfish, the higher the success rate of reproduction.
2. The breeding season of goldfish is usually in the warm spring, between April and June. Because the water temperature of domestic goldfish is generally relatively stable, it is necessary to artificially lower the water temperature a little before spring, and then restore the water temperature to 18-22 C, which is suitable for goldfish reproduction, to stimulate the estrus of goldfish and accelerate reproduction.
3. The suitable breeding water temperature for goldfish is 18-22 ℃. During the breeding period of goldfish, the water temperature must be suitable and stable. When the water temperature is less than 15 ℃ or more than 25 ℃, it is not conducive to the breeding of goldfish.
4. After spawning, the parent fish should be fished out in time, otherwise the parent fish will swallow the eggs.
