What kind of fish is my family, and how can I tell the difference between male and female? Anyone wh

The full name of your goldfish is called Heding Red, also known as Danding, the body type belongs to the butterfly tail, and there is a pearl Danding, the belly is very large and round, and there is also a red-crowned Lanshou, that is, there is no dorsal fin and the tail is very short, the kind of bloated body, I don't know which kind of fish you have, it is best to take a look at it.

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 the second characteristic star chasing during the spawning period, which is the easiest and most accurate time to identify the gender 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.

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.

Is it such a goldfish?

The slender ones are males, and the short ones are females.

There are different theories about the origin of the monk fish, but in general, there are predecessors of the monk fish in Malaysia, Thailand and even Taiwan. How to distinguish the male and female of a monk fish?

1. Monk fish is divided into male and female.

For the question of how to divide male and female monks, the following five points are generally used to distinguish them:

1.Thorny dorsal fin: The first to sixth spinous dorsal fins are thicker and rounder and are males, and if they are thinner and flattened, they are females.

2.Pelvic fin: touch the pelvic fin with your hands, the harder is the male, the softer is the female, because the female must use the pelvic fin to shake to provide oxygen to the eggs when breeding, to prevent the invasion of bacteria, and can be used to sweep away debris.

3.The sharper fish chest is more female, and the fish breast is more rounded and more male.

4.Body shape: Usually the thicker body of the fish is the male.

5.Genital pore: The genital pore protrudes in a V-shaped shape for males, and the genital pore protrudes in a U-shaped shape for females.

Second, the male and female of the monk fish.

It is a hybrid species, and the method of distinguishing the black spots on the dorsal fin is not accurate. However, the general method of distinguishing males and females cannot be used on the little arhats, so the original parental discrimination method is used to increase the probability of distinguishing the males and females of the little arhats.

Generally, the little male arhat is more courageous, and the little female arhat is easy to be frightened and blackened. In the case of underfeeding, the hand is waved gently and does not dodge, mostly males, and the black that continues to hide under the feet is usually female. When full of food, generally the small mutation is like a person approaching, most of the little female arhats will run around, and the little male arhats will shrink to the side corners.

The swallowtail is 8 10 cm long, the body color is light brown, the end of the tail fin is longer and pointed than that of the white-edged swallowtail, there is a vertical black line behind the gill cover, and the face has a light blue pattern. There is no obvious difference between females and males, and in terms of appearance, the fins of males are larger and sharper than those of females, and the abdomen of females is enlarged during the breeding period.

If you want to distinguish the male and female of a fish, you generally have to wait until it enters the breeding period and observe its abdomen or reproductive hole, so that you can know the sex. In addition, most females are larger than males, and males have special colors during the reproductive season. Of course, some other ways can be used, such as guppies can look at the anal fin, goldfish can look at the tail, and traffic light fish can look at the body shape.

There are many types of fish, and the way to distinguish male and female is different for different species. However, there is one method that is basically universal, and that is to observe the abdomen after the breeding period, and generally speaking, the abdomen is swollen in females. In addition, most fish females are larger than males, and during the reproductive season, males tend to be multi-colored or have beads on their bodies or pectoral fins.

1. Guppies: Guppies are common tropical ornamental fish, this kind of fish is not easy to judge male and female when they are young, usually the first color is male fish, in addition, if you observe the belly, the female fish can see the color, and the male is white. When it comes to the adult stage, there are many ways to tell the difference.

First of all, you can observe the anal fin, which is narrow in males and fan-shaped in females. Secondly, you can look for fetal spots, some of which are female fish. In addition, the tail proportion of the male fish will be larger, and the overall color will be more vivid.

2. Goldfish: Goldfish is a cold-water fish, with a wide variety of species, and the identification method is not fixed. First of all, you can look at the body type, usually the male is more slender, and the female is fat and short.

And the tail of the male fish is thicker and looks wide and flat. When swimming, males are more agile and faster, while females swim slower.

3. Traffic light: It is difficult to distinguish the sex of the traffic light fish, usually the male and female are more slender, and the female is thicker. However, this method is not very accurate, and it is only during the breeding period that the abdominal condition can be distinguished.

To distinguish between male and female fish, you can observe the belly, the female fish has a larger belly than the male fish, and most of the female fish are not as bright as the male fish. The genital orifice of the female is convex, whereas the genital orifice of the male is concave. Male fish will also fight during the reproductive period, and will often swim after the female.

When distinguishing male and female, the most obvious thing is that during the reproductive period, the belly of the female fish is usually larger than that of the male fish, and most of the female fish body color is not as bright as the body color of the male fish.

When the fish distinguish between male and female, usually the reproductive orifice of the female fish is convex, while the reproductive orifice of the male fish is concave, and during the reproductive period, some male fish will have star chasing, while the female fish does not chase stars.

It is also preferred to chase after the female, and the fins are larger than the female, especially the tail fin is wider than the female.
