Growth and reproduction

Guppy has strong adaptability, the optimum growth temperature is 22 ~ 24℃, it likes slightly alkaline water, pH is 7.2 ~ 7.4, it has a wide range of feeding habits, mild temperament, lively and active, belongs to pelagic fish, and can be mixed with other tropical fish. Peacock fish is easy to raise, but if you want to get a fish with gorgeous body color and beautiful figure, you need a wide water body, many aquatic plants, fresh bait and suitable water quality from the fry stage. The gonads of guppies mature at the age of 4 ~ 5 months, but their reproductive ability is very weak. In water with water temperature of 24℃ and hardness of about 8 degrees, it can breed 1 time a month, and the number of fry varies with the size of the fish, ranging from 5 to more than 100, and some fish will produce more than 200 young fish. When the female fish's abdomen is swollen and protruding, and obvious black fetal spots appear near the anus, it is a sign of labor.

Peacock is an oviparous fish. Strong reproductive ability and early sexual maturity. After feeding for 3-4 months, the young fish can enter maturity and reproduce. The time of sexual maturity is closely related to water temperature and feeding conditions. When guppies breed, larger aquariums should be selected and the water temperature should be kept at 26℃. The pH value is 6.8 ~ 7.4, and some aquatic plants should be planted at the same time, and then the fish should be released according to the ratio of 1 male 4 female. After the fish is in estrus, the abdomen of the female fish gradually expands and black fetal spots appear; At this time, the male fish keeps chasing the female fish. When the connector of the male fish is inserted into the reproductive hole of the female fish, the sperm is discharged for in-vivo fertilization. When the female fish's fetal spots become bigger and darker and her anus protrudes, she can be fished into another aquarium to give birth.

The temperature in the waiting box should be 1 ~ 2 degrees higher than the original water temperature, and moss or aquatic plants should be placed at the bottom of the box to provide shelter for small fish. The female fish should be taken out immediately after giving birth to avoid eating the larvae by mistake. Or wrap a plastic sheet around a funnel-shaped partition wall, immerse it in water, and put the parturient female fish in the funnel, so that the female fish can't eat the newborn fish and fall into the water outside the funnel.

Peacock fish spawn once a month, depending on the size of the female fish, each time they can spawn 10 ~ 120, and the annual spawning amount is quite large. When breeding, it should be noted that the fish kept in the same nest should not exceed three generations, so as to avoid species degradation caused by continuous inbreeding, making the offspring smaller and smaller and the tail fin shorter. It is best to introduce the same species of fish for purposeful distant hybridization to prevent subspecies from degenerating and achieve the purpose of improving species. But the life span of guppy is very short, generally only 2 ~ 3 years. The number of first births is generally less, about10 ~ 80; The second child gives birth to about 80 ~ 120. Prices range from a few yuan to dozens or even hundreds of yuan 1.
