Peacock fish (peacock fish) alias: rainbow fish, million fish, anchovy; Scientific name: Poecilia species: myxocyprinidae (viviparous); Origin: Venezuela, Guyana, West Indies and other places; Water temperature: 22 ~ 24℃; Hardness:10-30 dgh; PH value: 7.0. Temperament: gentle and lively male fish, with bright colors and rich colors. Some individuals have small blue-black spots on their body surface, surrounded by light-colored ring patterns, just like peacock's tail feathers, so they are called "peacock fish". Another feature of it is that it can breed almost all year round, once a month or every other month, with 20~ 100 young fish each time; After 4~5 months, the offspring are sexually mature, and the number of offspring of a pair of guppies in one year is amazing, so it is called "one million". The English names of guppies are Rainbow fish and Guppy, and the Chinese translation is often called "rainbow fish" or "Gobi". In addition, there are the common names of Moby Fish, Red Son and Longgang Fish. I. Origin and Ornamental Peacock Fish is native to Trinidad, Barbados, Venezuela, Guyana, northern Brazil and the West Indies in Central and South America. As an aquarium, fish culture began in 1862 and has a history of more than 100 years. 1908 was first shipped to Europe, and this kind of fish was kept as an ornamental fish in a fish tank in Germany. It may be a little late to introduce China. In artificial breeding, due to the influence of external environmental factors and artificial selection of inbreeding, its genetic factors are mutated, and varieties with different postures, colors and tails are cultivated, which is favored by people. Every few years, European countries hold an international ornamental fish competition in Germany, with peacock fish as the protagonist. Peacock fish is a kind of tropical freshwater fish, with bright colors like jewels and small and exquisite size, which makes people fondle it. Because of its strong adaptability and reproductive ability, it is suitable for family viewing and courtyard economic breeding. The appearance factors of guppies are mainly in color and fin shape, which are ever-changing through hybridization. If the body color is light red, light green, light yellow, mixed with purple, red, yellow, blue, black, gray and other colors; On some fish, they are full of shining luster and dazzling. When swimming in groups in aquariums, they are like shining stars in the summer night sky. Male fish are colorful and have their own characteristics, so it is difficult to find two similar male fish. Tail fins include round tail, flag tail, piano tail, torch tail, swallowtail, upper sword tail, lower sword tail, double sword tail, triangular tail, tooth tail, skirt tail, scissors tail, long tail, pointed tail and fan tail 10. There are also various patterns and colors on the fins, swimming proudly like peacocks. In addition to being ornamental, flying fishes are often regarded as mosquito killers in medicine and health care. Because it is addicted to food, it can effectively inhibit mosquito breeding. 2. Morphology, ecological habits and feeding methods The fish body is rotating, the front part is cylindrical and the back part is flat. The head is of medium size, the snout is pointed, the ventral fin is small, and the tail stalk is longer than the height. The morphology of male and female fish is very different. Male fish is thin, with a body length of about 4~5cm, short and high dorsal fin, and the tail accounts for about two-thirds of the total length; Some fins of the gluteal fin become mating organs; The caudal fin is wide and long, with various shapes. The female fish is stout, about twice as big as the male fish, and each fin is shorter than the male fish. The body color is monotonous and slightly transparent, and only the caudal fin is colored or mottled. Guppy has strong adaptability, and the water temperature is above 65438 06℃. If it is below 13℃, it will lie motionless at the bottom of the water, and if the water temperature drops again, it will kill people. It can tolerate dirty water, likes weak alkalinity and can adapt to neutral water. Its diet is omnivorous, and Daphnia, adults, ciliates, silkworms, plants and insects are all its favorite foods. Some people also eat some plant feed, such as moss kept in aquarium. Keepers can chop up spinach, blanch it with water and feed it to guppies. Female sturgeons are usually lively and easy to jump after being frightened; Especially when the male fish is chasing the female fish, it is even more lively. In order to obtain guppy with bright colors, beautiful figure and long tail fin, it is necessary to create a good living environment from larvae. 1, stocking density Because guppies breed too fast, farmers are often unwilling or not good at choosing, resulting in excessive stocking density. If the size of the aquarium is 39cm×30cm×30cm, it is generally appropriate to stock 20 fish. 2. Adjust the pH value of water quality to 6.8~7.4, and pay attention to changing water and removing dirt in time. 3. The optimum water temperature is 22~26℃ and should not be lower than 20℃. But when the water temperature is higher than 29~30℃, it will accelerate its aging. 4. Crustaceans with low feed and feeding methods, such as harvest worms, are the best feed for guppies, and algae food is also indispensable. Feed it 4 times a day, and feed it properly every time to prevent too much. 5. Environmental layout of the aquarium In order to accelerate the growth of guppies and promote the increase of fins, the aquarium should be as large as possible. Aquatic plants should be planted in the box, with bright light and clean and transparent water, which is not only beautiful, but also conducive to the healthy growth of guppies. Third, the breeding method 1, parent fish selection parent fish should pay attention to whether the body is strong, whether each fin (especially the caudal fin) grows and stretches, whether the body color is bright, whether the pattern characteristics are obvious, and whether the color is pure. With a good variety, you can start preparing. Usually guppies can mate when they grow to 4 months. 2. Choose a large aquarium for breeding, and inject water with appropriate physical and chemical characteristics (pH 6.8~7.4, appropriate hardness, water temperature 24~27℃) with water content of 80%. Plant aquatic plants or put banana leaves on the bottom of the box, and then put the parent fish in the ratio of male and female 1:2~3. Feed with nutritious and palatable feed such as fish and worms, 4 times a day. 3. The peacock fish that lays eggs is viviparous and has strong reproductive ability. Generally, sexual maturity is reached at the age of 4~5 months, when some fins of the male fish's gluteal fin evolve into pointed testis; The abdomen of the female fish is obviously swollen and protruding, and a black spot appears near the abdomen in front of the gluteal fin. This black swelling is a sign of labor. The darker the color, the closer it is to labor. In the * * * period, the male fish's tail unfolds like a "proud peacock", attracting and chasing the female fish with rotten colors. When mating, the male fish hooks the reproductive hole of the female fish with the hook at the front end of the connector; The mating time is about one second at a time, but it is more frequent. After mating, the male fish is taken out, and the female fish can reproduce several times in succession. The litter size of female fish varies with individual size and age, ranging from 20 to over 100. Small fish can swim and hunt after they are born. In the first week, ciliates and larvae can be fed, and in the second week, silkworms and dry feed can be fed. Young fish should be carefully raised in the first week, because the quality of feeding at this stage has a great influence on the future development of young fish. After giving birth, the female fish will rest alone for 3-5 days to avoid being chased by the male fish prematurely and being injured. When young fish grow to 3~4 weeks old, they can produce males and females and have mating ability. In order to ensure healthy offspring, male and female fish must be raised separately. The life span of guppies is short, and it has been aging for 2~3 years, and the life span of males is shorter than that of females. 4. Strain control In order to obtain exotic and beautiful guppies, two methods are adopted in seed selection: one is internal propagation, and the other is strain propagation. Inbreeding refers to the mating between closely related individuals. This method can purify and fix the genetic form to produce strains. However, this method should not be used continuously for more than 4 generations, otherwise there will be physiological defects due to genetic differences, such as fish becoming smaller, fecundity decreasing, and ugly color. Strain breeding is to let related fish mate with each other, but the blood relationship is not very close. By this method, fixed strains can be continuously propagated. In order to maintain excellent strains, it is necessary to guard against mixed species and * * * phenomenon, so male and female fish must be raised separately; If necessary, choose the right parent fish to breed in the aquarium, and make records-which female fish crosses which male fish, so as to choose which sex fish to backcross with the offspring in the future. Prevention and treatment of common diseases 1. White spot disease is caused by Pseudomonas multifida invading the skin and gills of fish. When a large number of worms are parasitic, many small white spots can be seen on the fish's body surface, fins or gills, and punctate vesicles can also be seen due to worm parasitism. After getting sick, the mucus on the surface of the fish increases, and the fish is thin and swims slowly, often floating on the water. Poor water quality, low water temperature, cold fish and so on can all cause this disease. Treatment: (1) add 1 drop of 5% methylene blue solution to 2L water and soak for several days; (2) Add 1 tablespoon salt into 4.5L water for several days; (3) heating the water temperature to 30 DEG C with an electric heating tube for sterilization; (4) If the condition is serious, the first and second methods can be used at the same time. 2, rotten mouth disease (rotten fin disease) This disease is due to the excessive pH of water quality, resulting in a large number of bacteria. The symptoms of sick fish are oral ulceration, fin tail rot and falling off, and in severe cases, the whole fin falls off completely. Treatment method: (1) add 1~2 drops 1% to 2L water? Soak in acridine orange solution for several days; (2) soaking in the same content of salt solution for several days; (3) Cut off the rotten fin with a pair of sterilized scissors. It is faster to cut the rotten fin from the root of the fin than from the tip of the fin. If combined with antibiotic immersion bath, the treatment effect is better. 3, water mold When fish suffer from white spot disease or epidermal injury, it will breed water mold. Myxomycetes multiply and grow into lumps, which are white or grayish white, like old cotton wool. Sick fish often suffer from impatience, dyskinesia, increased skin mucus, loss of appetite and finally die of weakness. Prevention and control methods: (1) Be careful during normal operation to avoid fish trauma; If there is trauma, directly wipe the affected area with 2% mercuric chloride solution; (2) Add 0.5g of potassium permanganate into 50L of water, soak it 1 time in the morning and evening, each time 10~ 15min.

On the other hand, BB focuses on personal situation.
Normal, just born, never opened his mouth.
And there is egg yolk water in my stomach.
So, there is no food to eat.
However, there was a D who spoke after a while. 7) Normal and strong mother peacock
The body will be bigger.
And the belly will be bigger. I wonder if he is pregnant.
You can observe whether his stomach is bigger than usual (before eating wild food). B. whether the mouth is on the rise. C.just a week before his death
He won't move.
Because my body is too heavy.
Often sink to the bottom. D, slowly pay attention to three pets.
You can see BB's eyes
