How to distinguish male and female swallow fish

       It is only in adulthood that the identification of male and female is obvious

       The most prominent feature of adult male fish is the protrusion of the head. The head of individual adult fish is quite high, which is easy to distinguish.

       In terms of body shape, the male fish is thicker, the abdomen is flat, the head is larger than the female, and each fin is slightly longer than the female.

       During the breeding period, the vas deferens will be exposed. The vas deferens are thin and short, and the direction is slightly forward.

       Adult females have smooth heads, some of them have bulges, but they don’t have a mushroom like dome like males, most of them have very small radians.

       The body is slightly thinner than the male, the abdomen is bulging, and the head is a little smaller than the male. Most female fish have shorter fins than the male.

       Reproductive period will expose oviduct, oviduct thick and long, direction slightly backward.

       In addition, according to many years of fish culture experience, most male fish are obviously more active than female fish since they are young. Especially when they are feeding, they are more active in snatching food. Therefore, in a litter, males tend to grow faster than females. When buying fish, most fish friends like to choose the biggest one. In fact, it’s easy to choose male fish. You should choose a few relatively small ones, so that the average ratio of male and female is higher. Although this is not absolute, but often breeding fish will have this experience.

       Identification of male and female

       It is difficult to distinguish the male and female in the juvenile stage, but the male and female characteristics are very obvious after 8-10 months of sexual maturity. The male fish has a well-developed forehead and a full and high abdomen. The male has a thin and pointed vas deferens, while the female oviduct is thick and round. Because the fairy fish is a kind of tropical fish that likes natural pairing, the successful fish often separate from the group and swim together and feed together, leading an independent life that only admires mandarin ducks but not immortals. This feature should be paid attention to by adult fish lovers. More time should be taken to observe the fish group to determine the complete pairing, but do not separate them. However, those who like to start feeding from the juvenile stage are better to buy 6-10 fish at the same time. Even if accidents happen during the growth process, a few of them will die or some will not grow well.

       Male: full forehead, high dorsal fin and long fins. Adult male swallow fish can be seen to be thin and strong during breeding. In terms of body size, male fish will look larger and more square than female fish, with larger angle of upper and lower fins.

       Female fish: the forehead and jaw of female fish are relatively smooth, and the belly of adult female fish is more bulgy than male fish. It can be seen that the female fish is relatively round during the breeding period.

       As shown in the picture, there are two fish, the male in the back and the female in the front. The head of male fish has obvious bulge, while the head of female fish is relatively smooth; the belly of male fish is flat, while that of female fish is full; on the whole, the body size of male fish is larger than that of female fish.

       Let me show you this picture is clear!

       718 summed up these three methods,

       But the premise of these three methods is: the fish is sexually mature. The body (the size of the fin removed) is at least 4cm or the fish is more than 10 months old

       Only when this condition is met can we tell the difference between male and female

       The method of distinguishing male and female by artificial swallow fish is basically the same, while that of black swallow, silver swallow, red eye diamond swallow, zebra swallow, Yin Yang swallow and panda swallow are basically the same.

       Hope to help you!

       1: Look at the size.

       2: Look at the head shape.

       3: After spawning, watch.

       (the premise of the above three methods: the fish is sexually mature. The body (the size of the fin removed) is at least 4cm or the fish is more than 10 months old. Only when this condition is met can we tell the difference between male and female. A small fish of two or three centimeters can’t distinguish male and female. Please don’t be misled by fish dealers. )

       The method of distinguishing male and female by artificial swallow fish is basically the same, while that of black swallow, silver swallow, red eye diamond swallow, zebra swallow, Yin Yang swallow and panda swallow are basically the same.

       The swallow fish is the fairy fish.

       It is difficult to identify the female and male in the juvenile stage, but the male and female characteristics are very obvious in the adult fish after 8-10 months of sexual maturity.

       It is characterized by:

       1. The head / jaw of adult female fish is smooth, while that of adult male fish is slightly protruding.

       2. The adult male has longer fins than the female.

       3. The abdomen of the adult female is larger than that of the male.

       4. In general, it will be exposed only after breeding. The female fish is thicker and rounder, and the male fish is firmer and thinner.

       How to distinguish between male and female in tropical fish

       Swallow fish, also known as fairy fish, angel fish. The body of the fish is rhombic, extremely flat, with straight trailing edge of caudal fin, dorsal fin and anal fin extending backward, symmetrical up and down, like an open sail.

       It is difficult to identify the female and male of the swallow fish in the juvenile stage, but the male and female characteristics are very obvious after 8-10 months of sexual maturity. The male fish’s forehead is more developed than the female fish, which is plump and high, and the abdomen is not as swollen as the female fish. Moreover, the male’s vas deferens are thin and sharp, and the female’s oviduct is thick and round. Because the swallow fish is a kind of tropical fish that likes natural pairing, the successfully paired swallow fish often separate from the group and swim together and feed together, leading an independent life that only admires mandarin ducks but not immortals.

       It is difficult to identify the female and male of the swallow fish in the juvenile stage, but the male and female characteristics are very obvious after 8-10 months of sexual maturity. The male fish’s forehead is more developed than the female fish, which is plump and high, while the abdomen is not as swollen as the female fish. Moreover, the male’s vas deferens are thin and sharp, and the ovipositing tube of the fish is thick and round.

       Two or three centimeters of small swallow fish can not distinguish the male and female. The male and female can be distinguished only when the fish reaches sexual maturity, at least 4cm in body (with fin removed) or more than 10 months of age. The characteristics are as follows: the forehead of male fish is more developed than that of female fish, and its abdomen is not as swollen as that of female fish. Moreover, the vas deferens of male fish are thin and sharp, and the oviposition tube of female fish is thick and round.
