What are the characteristics of the tails of female and male goldfish?

Goldfish have no characteristics to distinguish in the tail, they can only be distinguished in other parts as good, in terms of body shape: the male is thin and long, the female is short and thick, the hind abdomen is fat, and the breeding period is the most obvious;

Pectoral fin and gill cover: The pectoral fin of male fish is long and narrow, and there is milky white star chasing on the first fin and gill cover of pectoral fin in the pointed breeding season, and the pectoral fin of female fish is wider and rounder, and there is no star chasing during the breeding period.

Cloaca pores: males are small and narrow, jujube kernel-shaped, pointed at both ends, slightly enlarged in the middle, flat with the body surface or slightly concave inward, females are slightly larger and round pear-shaped, the end of the pear stalk is forward, close to the pectoral fin slightly convex outward.

Abdomen: Males feel harder to the touch, females feel softer.

Swimming posture: During the breeding period, the swimmer is active and actively chases other fish, while the female swims slower and is not as flexible as the male.

Difference in caudal peduncle: males are slightly thicker than females.

Male and female goldfish are mainly distinguished from the following aspects:

a) Differences in external morphology:

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) Difference in caudal peduncle: males are slightly thicker than females.

3) Differences in pectoral fins: careful observation shows that males are slightly pointed and long, and the first pectoral fin spines 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.

2) The difference in color: the male and female goldfish are slightly different in body color, the male fish is generally brightly colored, while the female fish is slightly lighter, and the male fish is more vivid in the reproductive development period.

3) Feel and movement: Gently support the belly of the fish with your hands, and feel a clear hard line on the abdomen of the male and female with the middle finger and ring finger, while the female has a softer abdomen. 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.

4) Star chasing: As the temperature rises, goldfish will have a second characteristic during the spawning period - star chasing, which is the easiest and most accurate time to identify the sex of goldfish, and it is also the easiest way to grasp a method of identification. 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.

Little goldfish are fun! They swim in the water, their big tails spread, like a beautiful princess in a long cape shaking in the water, fluttering, light and graceful. Sometimes they turn their heads up, their mouths open and closed, and their tails constantly wagging as if whispering to me.
