Basic information and feeding methods of parrot fish
Parrotfish is a hybrid of Azar fish and purple hot-billed fish. Because it is a cross between different varieties, the male blood parrot is infertile. The chromosomes of fish eggs can't be paired neatly, so the embryos can't develop into larvae. Theoretically, it should be possible to fertilize parrot eggs with male craters and azazel. Some female parrots can also cross with arhats. The parrot fish does not have the shape of an adult parrot in the larval stage. After three weeks, the shape of the larval fish will gradually change: the head is raised, the body becomes round, and the body color changes from black to gray and then slowly turns red. The life span can reach 4 ~ 5 years, but after the third stage, the physiological function of Nautilus will show signs of aging and lose its ornamental and commercial value.

(6) Candy parrot: By injection, the blood parrot appears in four colors: purple, blue, yellow and orange. But the color doesn't last. In addition, there are laser-stained parrot fish, which are written with the words auspicious, blessed, rich and longevity.
breeding method
The water temperature is 2 1 ~35℃, and 25~30℃ is the best. Parrotfish prefer fresh water, so it should be replaced as much as possible 1/5 fresh water every day. If the water quality is weak and refreshing, don't change the water frequently. Due to genetic factors, the respiratory system of the blood parrot is not complete enough, and its efficacy is only half that of other fish, so the dissolved oxygen in the parrot's aquarium is much higher. Mild temperament. Eat a lot, omnivorous, red worms, bumper shrimp, breadworms, small fish, Daphnia, earthworms, granules and other considerable feed can be fed. You can feed it two or three times a day. In order to ensure the bright body color, we should often feed the feed such as "Bao Zeng Hong". When new fish enter the tank, it will change color because of the sudden change of water quality, and it will gradually get better after adapting to the environment and adjusting the water quality. It is best not to mix other kinds of fish in the blood parrot's tank. It is best to set large aquatic plants, clay pots and heavy wood in the aquarium for parrots to hide. However, artificially trained parrot fish can change their timid habits: they often knock on the fish tank to make parrot fish form habits; You can only feed half the food and force them to come out for food; Mixed with bolder fish to drive them to move. Parrotfish have a strong sense of territory and often see fights between their own kind. Increasing the number of farms will reduce fighting. Because of its lively nature, parrots also like to fiddle with the sand at the bottom of the sea. Can be used with Mary, Pearl, Jianwei and Lili. Mixed culture of angelfish; Can be raised with gentle big fish. You can also mix with the smaller arhats since childhood, because they have a strong sense of territory. Adding penicillin and methyl blue will also make parrot fish pale. Increasing illumination, strengthening filtration, thickening filter material and heating to 28 degrees are all practical methods to maintain body color. Pay attention to the consistency of water quality when changing water newly. It is found that the parrot fish can be fed with coloring feed or shrimp meat when it fades, but the artificially dyed parrot fish will definitely fade after a period of culture, and it is irreversible. # Changing to a red tube can also make up for the visual defects.
