<> goldfish farmed by ordinary people like to be raised in pairs, because the even number is auspicious, and pairs also have the meaning of happiness. On the other hand, some farmers try to engage in some breeding, in order to further explore the growth and development of goldfish in the breeding process.
The knowledge and fun of fish farming. To be able to accurately distinguish the male and female of goldfish, in addition to mastering the basic essentials introduced in the book, the most important thing is to carefully observe the external morphology of different goldfish species, the differences in swimming and the changes in the external form of goldfish in different periods.
Male and female goldfish are mainly distinguished from the following aspects:
1. The difference between external forms:
1. Difference in body shape: male goldfish are generally slightly longer, while female goldfish have a shorter and round body. During the egg-bearing stage, females have larger abdomen than males.
2. The difference in caudal peduncle: males are slightly thicker than females.
3. The difference between pectoral fins: careful observation can find that the male fish is slightly pointed and long, and the first fin spines of the pectoral fin are thicker and harder; Females are short and round, and the first fin spines of the pectoral fin are not too hard.
4. The difference between the cloacal pores: from the belly upwards, the cloacal pores of male fish are small, narrow and concave; The cloaca of females is large, slightly rounded, and convex outward.
Second, the difference in color:Goldfish that are different in both sexes have slight differences in body color, and males are generally colored.
Bright, while females are slightly lighter, and males have a more vivid body color during the reproductive development period.
3. Hand feel and dynamics:Gently hold the belly of the fish with your hand, and feel a clear hard line on the abdomen of the male and the soft abdomen of the female with the middle and ring fingers. When walking past the edge of the pond, stomp on the ground and observe, the male swims fast and agile, while the female moves slower.
Fourth, chasing stars:As the temperature rises, goldfish are spawning.
The second characteristic will appear in the period - star chasing, which is the easiest and most accurate time to identify the gender of goldfish, and it is also the easiest way to identify it. The star-chasing of male fish appears on the first spine of the pectoral fin and the edge of the gill cover, and often there is a star-chasing on each fin bar of the entire pectoral fin, the front end is obvious, and the back one must be carefully observed. This kind of rough little white dot is star chasing.
Using the above identification methods, it is also necessary to rely on many years of breeding experience and careful observation to accurately distinguish the male and female of goldfish.

Identification of the sex of goldfish:
1. Chasing stars. Males: During the breeding season, a milky white version of the first fin and gill cover appear on the first fin and gills, which is called starchasing.
Female: No chasing star appears.
2. Body shape. Male: The individual is large, the body is slender, the tail root is thick, and the species characteristics are obvious.
Female: The individual is small, the body is short and thick, the tail base is thin, the distance from the abdomen is short, the abdomen is swollen, and there is a feeling of drooping.
3. Fin bars. Male: The pectoral fins are long and pointed, hard and powerful, and the front one is arc-shaped and relatively stout. The caudal fin is broad and powerful.
Female: pectoral fins broadly rounded. The caudal fin is comparatively smaller.
Fourth, cloacal pores.
Male: elongated and diamond-shaped, flat or slightly concave with the body surface.
Female: Slightly larger pear-shaped, with a forward-facing pear stalk and a slight outward protrusion.
Fifth, swimming. Males: Swim actively, often chasing other fish during the breeding season.
Females: Swim slower and are not as active and agile as males.
6. Touch. Males: The abdomen is hard to the touch.
Female: Softer belly to the touch.

1 look at the star, goldfish male in the breeding season will protrude a lot of white spots on the gills, this is the star, you can see who is the male fish, 2 look at the tail, this is obvious, the breeding season male fish chase the female, usually a female fish tail after there will always be 2 3 male fish chase, 3 look at the genital hole, this many masters use this trick, the genital hole is round for the female, the pointed for the male, 4 touch the abdomen, some fishing grounds are used, the abdomen is softer for the female, but this requires experience to accurately judge, but the accuracy rate is quite high, 5 look at the pectoral fin, The round is the female fish, the tip is the male fish, the technical requirements are not high, but the accuracy is not high, I hope it will help you, thank you.

First, it is necessary to grasp the water temperature. In winter, the fish tank should be placed in a sunny place to increase the water temperature, and when the water temperature is lower than 5, it can be covered with a straw curtain and cotton cover for insulation. If conditions permit, indoor tank cultivation can be heated with an electric heating rod and oxygenated with an oxygenator. >>>More
