What is the reason why koi fish have white gills and do not eat? 50

This is a bacterial gill rot, the first step is to isolate the sterilization water for sterilization, and the second step is to prepare yellow powder.

Soak the fish, remember to burst the oxygen, continue to take the medicine the next day, change half of the water on the third day to see the state of the fish, if it is not good, continue to take a medicinal bath until the fish is better.

The whitening of the gills of koi fish and the failure to eat may be caused by bacterial gill rot. Bacterial gill rot is a fish disease caused by the myxococcus bacterium that occurs in spring and autumn.

In order to ** this disease, the following measures can be taken:

1.Isolate the diseased fish and release sterile water, such as 2 ppm of nitrofuracillin or potassium permanganate.

2.Prepare yellow powder, soak the fish, remember to burst the oxygen, and continue to take the medicine the next day.

3.On the third day, change half of the water, see the condition of the fish, and if it is not good, continue the medicated bath until the fish recovers.

It may be that you have bacterial gill rot.

Symptoms: Severe blood loss of gill filaments of diseased fish, flocculent hyphae adhesion, gill filaments from red to white, gradually decay and dirt, and finally develop to full gills, sick fish show dyspnea, gills open and close rapidly, floating heads, and will soon die due to loss of breathing ability.

**: Caused by the pathogen is water mold, which generally occurs when the water quality is not clean.

**: You can choose 50 grams of salt, 50 grams of baking soda, mix in 10 kg of water, soak the diseased fish for 15-20 minutes. You can also choose gram malachite green, put it in 100 grams of water, and soak the diseased fish for 15-30 minutes.

Prevention: Regularly disinfect the fish pond to keep the water clean and reduce the chance of germs. The use of fresh feed and live biological bait has a significant effect on the prevention of this disease.

Change the water. The main symptom of koi fish eye whitening is that the koi fish look good, that is, there is a thin white film on the outside of the eye, like wearing a white eye patch, which is the koi blindfold.

The cause of the koi fish blindfold is bacterial infection and deterioration of water quality. Bacteria breed frequently in the water quality, and the koi itself can't stand the bacteria, coupled with the possibility of sterilization lights under the action, resulting in koi blindfolding, as well as water corruption, which is also a reason for the breeding of bacteria in the water quality, the water quality deteriorates, the koi itself will resist, may get other koi fish diseases, but also will make the koi eyes white, forming koi blindfolding.

1.Isolate the diseased koi This is the first step and a very critical step, mainly in the case that there is no large-scale outbreak of white hair disease in the fish tank, first take out the diseased koi and put it in the **tank separately**, so as to avoid a large area of white hair infection in the fish tank. After the sick fish is fished out, the whole tank is changed with water 1 4 or 1 5, and the whole tank is three thousandths of the salt, which is done to protect the koi carp that does not have white problems in the fish tank, and the whole tank salt 3 can also play a role in the overall disinfection of the whole tank of water and reduce the osmotic pressure of the koi, so that the fish can be in a better state.

2.**Cylinder heating to **cylinder heating, remember not to be too large every day, 24 hours a day can only be heated up to three degrees. If the temperature rises too quickly, the sick koi will hang up immediately due to the large temperature difference and weak constitution.

Keep the water temperature up to 30 degrees Celsius. The main effect of this is that if the bacteria exceed 30 degrees, they will not be able to survive, and they will die from the body of the sick fish and break away from the body of the fish.

3.Salt to the salt of the ** cylinder 5, its effect is the same as that of the main cylinder salt. It is to sterilize and adjust the osmotic pressure value of the fish body through 5 concentration of salt water, so that the white hair bacteria can quickly die and leave the fish body.

4.Medicated bath The final step is to kill the white hair germ with medicine. The drug I'm talking about here is the one I used when I was suffering from koi white disease, malachite green.

Soak the fish body with an appropriate amount of malachite green aqueous solution for 3-5 minutes and then put it into the ** tank. During the medicinal bath, it is necessary to keep the koi's and the oxygen ** sufficient.

The koi fish raised at home have a white problem, he should be isolated, the sick fish should be isolated, and then the good luck next door must leave, and then some of the sick can be done, and it is water conservancy for disinfection, you can use some light salt water, this angle, so that it will slowly be relieved, there is entertainment, and it will be slowly **.

Treatment. 1.If the number of diseased fish is small and can be operated locally, it can be soaked with iodine-containing disinfectant, such as a concentration of 20 mg l of povidone-iodine solution, or 2 mg of potassium permanganate mixed with 1% brine for 20 30 minutes;

2.or sprinkle the whole pool with 800mg l of salt and baking soda (1:1);

If you have white hair in your heart, the best way is to sprinkle medicine with the white hair spots of etiquette.

The first symptom of goldfish infected with bacterial gill disease is loss of appetite, often stops under the surface of the water, and shortness of breath, if the posterior edge of the gill cover is lifted, you will see white broken strontium filaments. Especially in crowded fish tanks, when the water quality deteriorates, goldfish are most susceptible to this disease, and the contagion is very high, so it is necessary to isolate the diseased fish.

**Method: 1. Replace part of the tank water, clean the filter and add a little salt into the tank, and stop feeding for a few days. Table salt** works by increasing the specific gravity of water, changing the osmotic pressure in the water, and killing bacteria and other pathogens through the change in osmosis.

2. You can directly use the commercially available Sera antibacterial and insecticidal agent, American sterilizer, queen whale antibacterial agent for goldfish disease, queen whale antibacterial agent and AZ00 antibacterial agent**, salt needs to be added to the water (2 grams of salt per 100 liters of water) to reduce the loss of goldfish body fluid from the rotten strontium filament to the fish, resulting in goldfish dehydration and death.

3. Fungi can also cause gill rot, so it is necessary to improve water quality so that the disease can be controlled. Filters remove particulate particles, prevent bacteria and fungi from growing, and keep the tank water clean, so a strengthened filtration system can prevent gill disease from occurring.

The above is about some of the best methods to share experience about goldfish rotten gills, I hope it will help you.
