First, the life of the guppies: The short-term and beautiful guppies have always been considered to have the vitality of the fish species, but its life is quite short, with an average of only about a year or so. However, it is rare that some improved varieties can survive more than one year. The life of a guppies is a beautiful and short life.
The short-lived phenomenon of guppies was discovered and analyzed from the aspects of breeding methods and breeds. For example, if the nutrition is not balanced, it will cause fish malformation or malnutrition. Although the high-temperature feeding will contribute to the development speed, it will also make the fish short-lived. This is also similar to humans. People living in the tropics usually do not live longer. In addition, in the improvement of breeds, if only the size, color, and appearance of the tail fin are the key targets, the most important “health problems†are often caused. If you just casually let this breed hybridize with that breed, the results of its improvement are unpredictable. To sum up, the bait is balanced and the water temperature is maintained at 22-24°C. It has been selected that a certain degree of mating has been fixed, so that the fish can be expected to sustain systematic breeding under healthy breeding.
Second, the purchase of fish: There are excellent "parents", not necessarily an excellent "daughter"; there is no good fish, there will be no excellent larvae Excellent larvae are the choice of broodstock. Choosing a broodstock is not only an appearance but also the quality of bloodlines. The fish species that are bred under systemization will clearly show the characteristics of each species, and the performance of the species will be met after the rigorous selection and elimination of the species has been maintained.
Under broodstock in a good system, most of the juveniles they produce have similar qualification characteristics to their parents. However, problems such as the growth, feeding, water management and other environmental and breeding techniques can also cause regrets. In contrast, larvae born out of poor system broodstock have a lower chance of having good quality. Even if a miraculously beautiful fish comes out, it usually has short-lived or weak fertility, often with malformation or weakness. Larvae, of course, can not continue!
In the selection of males, the angle of the tail fins is large, the color and pattern are eye-catching, the body is strong and well-proportioned, the tail shank is hypertrophic, and the female is chasing back and forth. The male with full vitality is the best choice.
In terms of females, the most important aspect is the shape, color and appearance of the caudal fin, all of which can represent the characteristics of the species. The best situation is that the mother fish that has produced the next larvae has a very bulky belly and a dark color, making it the ideal fish.
When you buy fish that are 3 to 5 months old, they are the most beautiful. If you choose a fish that is too young, you can't judge the appearance of the fish. In addition, fish that are more than 6 months old are not easy to use for reproduction. Although they are more beautiful and have a shorter lifespan, they do not provide you with long-term viewing needs.
You can find a wide variety of guppies in the aquarium at different prices. Some fixed system species are usually relatively high in price, but sometimes the species of guppies are already fixed, but if the yield is large, they can be bought at a cheaper price; similarly, there are also a few species that are scarce, although the system is not yet available. Fixed down, prices stay high. Therefore, the price of guppies is usually judged by the relationship of supply. You can consider purchasing according to your own preferences and the amount of spending power.
Third, breeding and breeding: prenatal separation, post-natal fertility in the female body of fertilized eggs mature, the abdomen will bulge, the lower abdomen will expand and dark, this is the so-called "pregnancy state." When the female swims upstream and downstream next to the aquarium, when abnormal actions occur, it is a precursor to the birth. At this time, it can often be seen in the female lower abdomen with juvenile fish and its large eyes.
In this case, if there are other aquariums, it is best to keep them separate from the males so that they will not jump out of the aquarium hysterically after being chased by the males. After the healthy females confirm their fertilization, they should be separated from the males and fed separately. When the calving period is close, they are put into spawning aquariums or spawning boxes. The abdomen was not imagined when it was first produced. . Normally, females and males will be able to give birth after about a month.
When males and females are polycultured, they are likely to give birth less than two months of age. In addition, once mating females, even if there is almost no contact with male fish, there will be three litters. However, more than half of the fish of the albino system are ovulated after the third time, and if they no longer mate with the male fish, they will not be born.
About 21 to 25 days of healthy females is a reproductive cycle. However, it will vary depending on the water temperature or the variety of whitening. The number of litters differs depending on the breed and the system. The number of litters is about 10 at the time of first birth, about 20 to 30 at the second, and about 30 to 50 at the third. For example, the German yellow-tailed dresses produced only a few varieties at a time, and one of them produced nearly 100 females at one time. However, the larger number of litters does not mean that it is ideal.
A litter box can be prepared for littering or a litter box can be used. Aquariums can be filled with plants to create an environment conducive to the birth of a female. Place it in the new water, increase the temperature by about 2°C, and give birth one or two days after the stimulus. Prosperous plants are the best hidden source for juveniles, but it is important to note that females may inadvertently eat larvae, especially in the albino system, because their eyesight is weak, and juveniles have a similar body color to bait. So it's easy to eat.
The farrowing box is lightweight and easy to use, but it should not be put in too early. It is most appropriate to put it on the day before the expected date of production. After finishing the farrowing, the mother fish should be removed immediately in order to maintain a wide space.
After the farrowing is over, the mother fish should be fully rested in other aquariums and carefully consider whether or not to allow the females to re-grow, so as to avoid excessive fish in the aquarium and inconvenient management.
The juvenile’s physical condition within three weeks is very important and it is necessary to adequately feed it several times. In addition to paying attention to nutritional balance, we must also avoid deterioration of water quality. Juveniles stay in the farrowing box for about 10 days and can use straws to remove the remaining bait or impurities to maintain water quality. Then put in a 30cm small aquarium, the aquarium does not need to be too large, 30cm can be.
You can drop a few drops of methyl blue into a litter of aquarium to achieve the disease prevention effect.
Fourth, the selection of juvenile fish: out of gender discrimination, precocious puberty and physical abnormalities juvenile fish produced about three weeks after birth can distinguish between male and female, but if you can pick out separately before this, it is better.
In addition to the late-development varieties such as the albino system and the German yellow-tailed dress, if the other fish species cannot distinguish the gender after more than three weeks, it is a sign of stunting and debilitating physical condition!
From the body type, it can be judged by the spots on the base of the caudal fins of males, and the black spots on the lower abdomen of females are also easily distinguishable features. Juveniles in the light of a small aquarium, from the side, the bottom are very easy to observe the characteristics of the body, if there is malformation, stunting, when the front of the caudal fin disease occurs, need to be done as soon as possible.
When the guppies are precocious, when their parents are in the same aquarium, the male larvae will chase their mothers within a month and woo their mothers! Most of the males that are so precocious do not use it as a kind of fish because they will stop growing in the middle of the city and keep their hours until they become adults. Therefore, they cannot be used as a kind of fish and should be treated as soon as possible. Separate the male and female fish early to ensure the initial operation of the virgin female system.
If you are not breeding for business reasons, just for the sake of interest, and nurturing the next generation in stages, then it is necessary to properly select male and female fish to maintain the larval fish standard. To create a good guppies offspring, must be fully managed to maintain a good environment for growth, and observe carefully every day, once the fish with abnormal or stunted, it is best to be eliminated as soon as possible.
Between 1 and 3 months of birth, the growth of the fish has unimaginable changes and care must be taken. After about two months of development, the color of the guppies is quite stable and the tail is very large. At this time, care must be taken to ensure that the guppies will become a candidate for rearing fish. If the fish is found to have a large body, a small caudal fin, asymmetry in the whole body and a neutral phenomenon, it must be dealt with immediately.
The size of males and females is roughly the same during this period. After three months, the females are usually larger than the males. After the farrowing females will be larger than the males.
After repeated rigorous screening and elimination, about four months of age can be selected to breed a parent, giving birth to the next generation. That is, when it is about four months old, it is the most suitable mating period. The mating of young parents produces the best larvae. Among them, you can pick out first- and second-generation good-quality larvae (the first generation of mother fish is called the first generation, and the second generation is called the second generation. generation). Healthy females can also produce third- and fourth-generation good-quality larvae. However, the proportion of malformations in later-produced larvae will increase.
It is not until about two months later that the male fish will show its characteristics. At this time, the color of the body or the appearance and shape of the caudal fin has been clearly seen, and the state of the adult fish can be imagined.
The tail male of the triangle tail is linear in the upper and lower parts of the caudal fin, has an angle, the tail is not circular, and the caudal fin of the adult fish is large and beautifully developed. The color or pattern of the central part of the caudal fin is not obvious, and it is not favored, and when the front of the caudal fin is transparent, it means that it is still growing up until the tail of the adult fish has turned black. In addition to the tail fins, the dorsal fins must be the focus of attention. It is very important whether the shape of the dorsal fins is carried out. If the dorsal fins are too rigid, they will not develop even if they become adult fishes. In general, besides the large dorsal fins, the flexibility of the dorsal fins must not be lacking. .
If fish with abnormalities such as back flexion and body shape malformation are found to be eliminated, there is a high possibility of inheritance, and the acquired disorder caused by partial eclipse or insufficient light quantity is not easy to be passed on to the next generation, but it should be avoided. The species of fish, in short, choose healthy and beautiful individuals to use as needles.
As mentioned above, the quality of the male fish can be assessed by its appearance. To select a female, it can be much harder! The appropriate selection of female fish has an absolute influence on the quality of the next generation.
Excellent females should have a healthy body and be able to inherit the characteristics of the male fish to their offsprings. Therefore, they have nothing to do with their appearance, body or tail being too small, and whether the color looks beautiful or not. Basically, when the female tail crest swings, it stretches very much, and the caudal fin is nearly ideal. However, with a high degree of immobilization, the tail fins will have a faint appearance and spots. Since each species has its own characteristics, it is very important to select females with basic concepts.
The short-lived phenomenon of guppies was discovered and analyzed from the aspects of breeding methods and breeds. For example, if the nutrition is not balanced, it will cause fish malformation or malnutrition. Although the high-temperature feeding will contribute to the development speed, it will also make the fish short-lived. This is also similar to humans.

Tuberculosis (TB) is a potentially fatal contagious disease that can affect almost any part of the body but is mainly aninfection of the lungs. It is caused by a bacterial microorganism, the tubercle bacillus or Mycobacterium tuberculosis.Although TB can be treated, cured, and can be prevented if persons at risk take certain drugs, scientists have never comeclose to wiping it out. Few diseases have caused so much distressing illness for centuries and claimed so many lives.
