How to raise the grass tail peacock fish?

The fish is very frightened after entering the tank. It's better not to turn on the strong light line such as the tank lighting, and not to disturb it. For example, when watching, you can't point and point too much. Before picking up the fish, you must do enough preparation work. After entering the tank, don't always run around the tank. Remember not to feed the fish that day! Don't change the water, and observe its state. Generally speaking, on the first day, the fish will recover some state, such as looking for food, chasing spouse, etc. If the condition is not good, 1% saturated brine can be added. Observe for a few more days. Generally, if the fish are in good condition within a week, they can feed a little less live bait if they are looking for food and chasing after their spouse. It means that they should not feed too much! It is best to open the bait to eat live food, such as rich year shrimp, etc. artificial bait is not recommended because of digestion difficulties. It can change 1 / 10 of the water. The water temperature in winter is 1-2 degrees higher than that in the cylinder. In summer, it is 1-2 degrees lower. This is also the way to master the temperature when changing water in a year. If the condition is not good, do not feed, continue to observe. In case of floating head, it is necessary to consider whether the stocking density is excessive. Separate the cylinders in time. If there is no problem and the food is in good condition, it is better to feed less in the morning. If the food cannot be eaten, it should be fished out in time, and the feeding time of the fish should be controlled within five minutes.

For bait, it mainly refers to the type of bait, the amount of feed and the times of feeding every day, as well as the adjustment of the variety and the amount of feed increasing with the growth of fish age.

Peacock fish is not fed on the day when they are just born, because one is to make them adapt to the environment first, and the other is to have yolk sac which has not been absorbed completely. Ha ha, peacock fish is born with eggs. From the second day on, it is better to open the mouth with the larva of live and abundant year shrimp, which is rich in nutrition and easy to absorb, and has the effect of promoting defecation. In this period, the fish should eat as much and as much as possible, and the belly should be hemispherical. At this time, a little live bait can be kept in the tank. Brother summed up a proverb that "try to keep up in 4 weeks, feed hard in February, eat enough in 3 or 4 months, and feed less after May". Because the brother has another job in the body, so in this period, he can only take time to feed twice in the morning and evening, especially after feeding in the morning, it is better to keep a little live bait in the fish tank. During this period, if according to the standards of professional players in Europe, America and Japan, they should be fed 6 to 8 times a day, with an interval of about 2 or 3 hours each time. Such feeding methods can be used for reference by professional players.

The growth and reproduction of malachite

Malachite has strong adaptability, the most suitable growth temperature is 22-24 ℃, likes micro alkaline water quality, ph7.2-7.4, has a wide appetite, mild temperament, lively and active, belongs to the upper layer fish, and can be mixed with other tropical fish. Peacock fish is easy to raise, but to get a bright body and a beautiful body, it needs a wide water body, more water plants, fresh bait, appropriate water quality and other environment from the fry stage. The gonads of peacock fish are mature at the age of 4-5 months, but their reproductive capacity is very weak. They can reproduce once a month in the water with a temperature of 24 ℃ and a hardness of about 8 degrees. The number of fry produced each time varies according to the size of the fish. There are less than 5, more than 100. Some fish will produce more than 200 young fish. When the female's abdomen bulges and bulges, and there is an obvious black fetal spot near the anus, it is a sign of labor.

Malachite is an egg viviparous fish. It has strong fecundity and early sexual maturity. After 3-4 months of feeding, the juveniles can enter the mature stage and reproduce their offspring. The late or early sexual maturity is closely related to the water temperature and feeding conditions. When the peacock fish propagates, it is necessary to choose a larger aquarium, and keep the water temperature at 26 ℃. Ph6.8-7.4. At the same time, a variety of aquatic plants should be used, and then the fish should be planted according to the ratio of 1 male to 4 females. After estrus, the female's abdomen gradually expands and black spots appear. At this time, the male continues to chase the female. When the male's adapter is inserted into the female's vent hole, the sperm is discharged and fertilized in vivo. When the female's fetal spot becomes large and black and her anus protrudes, she can be fished into another aquarium for labor.

The temperature in the incubator should be 1-2 degrees higher than the original water temperature. Moss or water grass should be placed at the bottom of the incubator to provide a shelter for small fish. After giving birth, the female fish should be fished out immediately to avoid eating the larvae. Or plastic pieces should be enclosed into a funnel-shaped wall, immersed in the water, and the female fish should be placed in the funnel, so that after the larvae are produced, they will fall from the hole under the funnel into the water outside the funnel, and the female fish will not eat the larvae.

According to the size of the female, peacock fish can produce 10-120 larvae once a month. The number of larvae produced in a year is quite large. When breeding, it should be noted that there should be no more than three generations of fish in the same nest, so as to avoid the degradation of breed caused by continuous inbreeding, resulting in smaller and smaller fish body and shorter tail fin. It is better to introduce the same species of fish for purposeful distant hybridization in order to prevent the degradation of sub species and achieve the purpose of improving varieties. But the life span of peacock fish is very short, generally only 2-3 years. Generally, the number of first birth is relatively small, about 10-80; the number of second birth is about 80-120. The price ranges from a few yuan to tens or even hundreds of yuan.
