Recently, in the backstage of our official account, many fish friends asked the same question, that is, what about the koi lying in the tank? In the process of raising koi, it is quite common for koi to lie down in the tank. Koi lying down is not necessarily a problem with koi, sometimes it is just a normal physiological reaction, sometimes it may be due to water quality, fish disease and other reasons. Therefore, we have to analyze first, what is the cause of the koi lying tank, according to the different lying tank, to make the correct treatment.

The beloved carp of "Prince", a fish friend of Wechat group.

1. Koi lying in the tank caused by water quality

Most of the koi lying in the tank caused by the water quality is caused by the large fluctuation of the water quality of the brocade carp, mainly because of the great fluctuation of various indexes in the water quality of the brocade carp.

When changing water, many fish friends change water too fast, or change a large number of cleaning filter materials, resulting in the koi can not quickly adapt to the new water quality, it can also be said that the koi lie down because of the stress reaction.

In addition, the koi will lie down after changing the water in the old water tank. The excessive pH pH in the water will also cause the koi to lie down. The so-called exceeding the standard means that the pH value of the water in the fish tank exceeds or is lower than the pH value suitable for the koi. Of course, when adjusting the pH value of the water quality, it is best not to exceed 0.4. If it exceeds 0.4, the koi will easily lie down in the tank.

Solution:

1. Pay attention to filtration and sterilization, open the filter throughout the day, cultivate the nitrifying bacteria well, and the water quality will be clear.

2. The feeding density of koi should not exceed the carrying capacity of the filtration system to avoid the deterioration of water quality.

3. If the drug is administered, generally do not administer the drug in the whole tank, which will pollute the water quality.

4. Change water.

(1) partial change of water

It can stimulate the appetite of fish and partly improve the water quality by putting off the amount of 1ax 3-1 stroke 2, and then adding new water directly. This is a method to maintain the water quality of koi.

(2) change all the water

The water quality stabilization time of koi is closely related to the water temperature, so the new and old water temperature should be balanced and the temperature difference should be controlled at 1-2 degrees Celsius.

Second, the new koi fish does not adapt to the environment caused by the tank.

The new koi does not have good water, that is, it does not completely adapt to the water quality of the new environment, so putting the koi into the fish tank will cause the koi to lie down in the tank.

If the breeders' aquariums have koi that have been raised all the time, and the new koi have adapted to the new water quality environment after passing through the water, but have no understanding of the creatures in the fish tank, and are not familiar with the old brocade carp that live together in the new environment, they will form a posture of not wanting to move and being lazy, and will form a lying tank.

In addition, the new koi did not carry out disinfection and sterilization, and formed cross-infection after entering the tank, which is also the reason why the new fish do not adapt to the environment.

Solution:

1. Disinfect the fish tank

Both new and old cylinders need to be sterilized.

2. Bubble cylinder

The main purpose is to check whether the fish tank is leaking and take away the smell of glass. Generally, the new tank needs to use potassium permanganate bubble tank for more than 24 hours. It should be noted that the fish tank should be filled with water when bubble tank.

3. Raising water

During the period of raising water, the filter material, water pump and air pump in the filtration system should be fully equipped and the air pump should be opened 24 hours a day. In winter, turn on the heating rod and adjust the temperature to the suitable temperature for koi as much as possible.

To cultivate nitrifying bacteria, explosive oxygen is needed. At this time, you can start to put the fish into the tank to see the reaction of the fish in the tank. At first, the fish may not adapt to the environment, and the fish will run into the tank at random. This is normal. Just wait patiently. When the water becomes turbid and then clear, it will take about a week to 10 days to slowly establish the nitrification system.

During this period, tank-breaking fish may be sacrificed, which is normal. It is best to change the water twice a week. When you see the water becomes clear, you can put in your favorite koi. As long as the temperature is suitable, the water quality is good, the environment is comfortable, and adapt for a few days, the koi will not lie down.

III. Lying tank caused by brocade carp disease

The more common ones are sleeping sickness, koi colds, brocade carps, intestinal problems and so on.

1. Sleeping sickness

Watch the koi flip as if it were asleep. You will see the belly of the fish, stop swimming, and there will be edema and sunken eyeballs. It may be due to the fatigue and chronic malnutrition caused by drastic changes in the environment, relocation and long-distance transportation of koi. When the koi is moved from the fish pond / farm / pond to the winter pond, sleeping sickness will cause the koi to lie down.

2. catch a cold

When the water temperature of the koi pond / tank changes too much, it will make the koi catch a cold. Koi cold will appear to shrink the fin, swimming slowly, to the middle of the body will appear to shrink the fin, later began to swim alone, floating in the corner of the fish tank or lying in the tank, the body will be accompanied by congestion, bloodshot and other symptoms.

3. Parasite / intestinal problems

At first, there will be the phenomenon of koi lying on the cylinder. When koi gets internal mailing, this is different from outward mailing, which can not get rid of some parasites by scrubbing cylinders, which will cause internal problems in koi, similar to intestinal problems, indigestion, emaciation, and do not like to swim. Lying lazily at the bottom of the cylinder.

There are other koi diseases, although they will swim in the early stage, but if there is no treatment in the later stage, there will also be the phenomenon of lying in the cylinder.

Solution:

1. Koi colds

When changing water, it must be slow, and the temperature difference of water should be kept at 2-3 ℃. The most important thing is to actively prevent the change of water quality temperature difference caused by the intersection of seasons. As long as the water quality does not change too much, koi generally will not catch cold.

2. Bacterial infection

To avoid koi injury, but also to maintain good water quality, when eating, we should also pay attention to eat less and eat more to avoid enteritis, and when feeding live food, we must pay attention to sterilization and disinfection. These are the sources of bacteria, as long as they are contained. Koi will not have bacterial infection, naturally there will not be the phenomenon of lying down.

3. Cross infection

Insecticidal prevention in new fish and crisscross seasons; enhance water flow, maintain clean and stable water quality, reduce stimulation to Gill or body surface tissue, reduce the chance of parasitism, and treat diseased fish in isolation to prevent infection.

4. Parasites

Keep the water well and then raise fish, and when choosing fish, you must observe carefully, do not buy sick fish, but also change water frequently, the density of koi raised should not be too high, and there should be a perfect filtration system, so as to avoid parasites and cause koi to lie down.

Fourth, the lying tank caused by the hibernation of koi.

To be clear, koi will not hibernate, just because the water temperature is too low in winter, which slows down the metabolism of koi, so it is not very active. Koi belongs to cold water fish, and the lowest water temperature that can be adapted is 2 degrees. As long as the water temperature is lower than 10 degrees, the koi is not very active. At this time, the koi is inactive and often has the phenomenon of lying down. This is a normal physiological reaction, which can accumulate energy for the koi. In addition, if it is a fish pond, the water temperature at the bottom of the pond is higher than that of the water surface, which is conducive to the survival of koi. There is not much difference between fish tanks.

If the water temperature is too low, koi is not only inactive food intake, less excretion, but also may lie down, these are very normal, you do not have to worry.

Solution:

To solve the problem of partying in winter is very simple, that is to heat up. When the temperature reaches the most suitable temperature for koi, koi will not lie down any more. In addition, when the water temperature is low, the koi will lie at the bottom of the fish pond / tank for a long time, and the fish belly will constantly rub against the bottom of the pond, which will cause abdominal congestion and ulceration, so if the weather in the north is too cold, it is best to be equipped with a heating rod.
