It is more difficult to distinguish male and female goldfish without maturity, and the keeper can first look at their color, generally speaking, the color of male fish is relatively bright, and the color of female fish is a little darker. You can also look at their tails, the tails of males are thick and the tails of females are small.

If it is a goldfish that has reached the breeding period, it is easier to distinguish between male and female, first of all, the abdomen of the female fish will be slightly raised, and it is soft when pinched by hand, because they have fish eggs in their abdomen. Male fish will have the characteristic of "chasing stars" when they enter the breeding period, and on the first fin of their pectoral fin, there will be a bump of white spots, which will only appear in male fish, and only appear during the breeding period, after which the white spots will disappear.

If goldfish are not in the breeding season, keepers can tell the male and female by their tail and color. The male fish is relatively bright in color and has a thick and long tail. Females tend to be darker in color and have smaller tails.

If the goldfish reaches the breeding period, it is easier to distinguish between male and female. When the male fish reaches the breeding season, they will have the characteristics of "chasing stars", and a white bump will appear on the fin. When the female reaches the breeding period, her belly will become bulging and it will be relatively soft to the touch.

Male and female goldfish have slight differences in body color, males are generally brightly colored, while females are slightly lighter, and during the reproductive development period, males have more vivid body colors.

Goldfish males and females are easy to identify during the breeding season, and females will have larger bellies, while males will not. If it's not the breeding period, you can look at the body size, the general male body is slender, and the female is relatively short. As a traditional ornamental fish in China, it has a history of more than 1,700 years, with many varieties and rich colors, and is divided into four strains, namely grass species, literary species, dragon species and egg species.

We can use the method of looking at the body shape and probing the belly of the fish to identify the male and female. Males are slightly larger and longer than females, with slightly pointed fins, and the head males are plump and raised. Females are the opposite!

Basically, there is a string of obvious white protrusions on the first hard bone of the pectoral fin, commonly known as star chasing, and such a fish is a male fish. Some males have obvious characteristics not only on the pectoral fins covered with dense star chasers, but even on the gill covers, there will be a lot of star chasers.

The female fish, on the other hand, does not have star chasing on the pectoral fin, but is very smooth. This sexual trait is also most evident during the breeding season. But there are also rare cases where the female fish also has star chasing.

Therefore, if you want to accurately distinguish male and female, it is not enough to look at only one feature, but also to look at it comprehensively. However, the vast majority of fish can judge male and female by whether they are chasing stars or not during the breeding season.
