Why do koi fish pretend to be dead, and why do koi fish die

For the fish tank or cement pool that has just been bought, it must be carefully washed before use, and it must be filled with water and soaked for several days to 1 week for "annealing" or "alkali removal"; Park pools or earthen ponds should be regularly disinfected with quicklime. In order to make the water quality of koi fish meet the requirements, one is to dissolve 12 grams of phosphoric acid in 50 liters of water, and soak the new pool with such water for 1 2 days to achieve the purpose of alkali removal. Then rinse with salt water or potassium permanganate solution and fill it with tap water and soak it for about 1 week (to promote its early production of moss), change to new water and a small amount of old water, put a few second-class fish for trial rearing, and then put in a few koi fish to raise.

Dissolve alum in pool water (its concentration must reach the degree of alum saturation), after 2 to 3 days can achieve the purpose of alkali removal, and then change to new water, it can be used. For containers that have not been used for a long time, they should be disinfected and soaked in salt water or potassium permanganate solution before use.

Whether it is a breeding pond or a wintering pond, the koi fish must be disinfected and cleaned before entering the pond. Quicklime should be used to clear the pond before releasing koi fingerlings in the culture ponds. Before releasing fish in the wintering pond, drain the pond water, remove attachments and dirt, and sprinkle the whole pond with bleach solution for disinfection.

The amount of quicklime per 667 square meters is 50 75 kg for a pond with a water depth of 10 cm, and 130 150 kg per 667 square meters when the water depth is 1 m. Koi fish can be released about 7 days after the pond is cleared.

Tea cake Qingtang first mash the tea cake, soak for 1 day, and choose a sunny day to splash the whole pool. The amount of water used per 667 square meters is 40 50 kg per 1 meter water depth. Koi fish can be released about 10 days after the pond is cleared.

The amount of bleaching powder used in the pond is 20 grams per cubic meter of water. Once the bleaching powder has dissolved, sprinkle the whole pool immediately. Koi fish can be released about 10 days after the pond is cleared.

Quicklime and tea cake are mixed with clear pond water depth meters, 50 kg of quicklime and 30 kg of tea cake per 667 square meters. First, mash and soak the tea cakes, then mix in quicklime and wait for it to absorb water and dissolve, and then sprinkle the whole pool. After 1 week, you can test the water with koi fish.

Quicklime and bleaching powder mud together clear pond water depth of 1 meter, 65 80 kg of quicklime and kilograms of bleaching powder per 667 square meters, the same usage as bleaching powder and quicklime pond, about 10 days after clearing the pond can be put record fish.

After all the work is done, we can carefully put the koi fish into the koi fish pond or koi fish tank. Raising it in this way can reduce unnecessary trouble, and koi fish are special**.

Not fake death, it's because"Stand"Don't get up.

1 If you are sick, it is recommended to check the fish for lesions and then look at the water quality problems.

2. There is something wrong with the motor nervous system and I can't coordinate my movements. However, there should be very few problems, mainly in terms of illness, you still have to check them one by one.

It's a very good fish, and if you keep it in a tank, it's probably not good for water quality, and you have to build an ecosystem.

There are two possibilities: if you get sick, you are dying; The motor nerves or lateral lines are destroyed and they can't coordinate their movements, but they don't die.

There are many causes of death for koi fish, and here are a few of them:

1.Water quality problems: some cities have poor water quality, water plants use a large number of sterilization and detergents, fish will be poisoned if they are not adaptable, so there are skills such as drying water, waterfall, breaking into the tank, etc., the most easy to make fish poisoning is the chlorine in the water, new water with an appropriate amount of dechlorinated water is a quick solution to the problem, but be careful not to overdose.

2.The problem of water temperature difference: This problem is most prominent when the weather is cold, koi can survive in the water temperature from 2 to 35 degrees, but the adaptability to the instantaneous water temperature change is extremely poor, and it is easy to die suddenly if it exceeds 3 degrees. In case of emergency, hot water can be added to cold water from a water heater and temperature measurement with a thermometer.

3.Pay attention to hypoxia: Koi fish die quickly from hypoxia and are not aware of disease.

The biggest feature of hypoxia is the floating head, and the fish should be pumped or even changed as soon as the head floats. Another characteristic of koi fish hypoxia is difficult to grasp: the same amount of water begins to be inflated and does not float, and after a period of breathing, it suddenly does not inflate, and the fish instead lacks oxygen and floats.

This point should be taken with special attention.
