The koi fish turned red on their tails! And don t eat much? What to do??

It is really difficult to cure a fish disease, because the constitution of the sick fish is very weak, and the fish disease will be more serious if the medicine is not used properly. Fish diseases are mainly caused by long-term poor water quality, just like people, if they live in an environment with bad air for a long time, they are also easy to get sick. Clear water does not mean that there is no ammonia poison in the water, the key to raising good fish is filtration, filtration is to filter fish feces, the toxins in the water are produced by fish feces, and only by removing the ammonia of fish feces can the water body be stable and clear, and the fish can be healthy and less sick.

If there is a lack of eczematic area of nitrifying bacteria in the tank, there are very few nitrifying bacteria, and the fish feces can not be treated in time, the ammonia content of the water body is high, and the fish will live in the water body with ammonia poison for a long time, and the physique will slowly become weak and it is easy to be attacked by the virus in the water. Fish are prone to illness and anorexia, and the water is easily cloudy. Some hazards do not manifest themselves all at once, but have a process of accumulation, which generally begins with fish with weaker constitutions.

Yongqing filtration understands that this filtration system has the function of automatically cleaning fish feces, which will help.

Is it bloodshot? Or ordinary red, reddening is a physiological phenomenon, bloodshot is a water quality problem, often change the water to strengthen the water quality.

This is generally its physiological phenomenon, don't care about it will be fine in a few days, if you can't do it anymore, you can only go to a veterinarian.

For koi fish with red blood capillaries and broken tails, the best methods are: 1. Put nitrofuracillin powder gram in 100 kg of water for immersion and disinfection, and the condition can be alleviated after repeated medication.

2. For such diseases, you can also choose 1% malachite green aqueous solution to apply to the place where the tail fin is broken, once a day, for 3-5 days, it will get better.

When using the above methods, if you use a salt bath, the effect will be better. If you thoroughly understand the problem of how to raise koi fish, it will also reduce the occurrence of koi fish disease.

In fact, it can be prevented for koi fish to have red blood capillaries and broken tails, that is, when koi fish are farmed, good water quality must be maintained, and new fish must be sterilized and sterilized to prevent cross-infection, and it is advisable to raise them at low density.

The body surface of the koi fish is "congested", and the teacher teaches you a trick to solve it.

Put some coarse salt first, and if there is a rotten tail, buy fungicides from the fish store.

The koi tail is congested and turns red.

**Method: Keep the environment stable, let the koi fish rest for a few days, maintain the water quality during the period, add three thousandths of salt, and it will be fine for a few days. The harm is not great, if it is beaten by other koi fish or hit the cylinder congestion, pay attention to prevent bacterial infection, and whether there is a wound on the body surface, you can choose to use yellow powder if there is a wound.

One is that, as mentioned upstairs, the normal changes in the development of a fish, like a peacock's long tail, are a gradual process.

The second is the appearance of blood streaks and blood spots. It may be that you are not suitable for the water quality, so you should maintain good water quality, change the water regularly, and rest for a few days. If it becomes more severe, it may be sick, you can put an appropriate amount of coarse salt in the water, or oxytetracycline, penicillin injection, etc.

The amount is about 1,200 per person, and every day I take medicine and change some water.

Koi fish change color is normal, and it may change in the future, which is also a special charm of the koi.

In this case, it is likely to be caused by malnutrition, so you should usually feed it more nutritious foods.

It is possible that the water is not well maintained. If it is an emergency**, first put some wild yellow powder, or take out the fish and apply chlortetracycline eye ointment and other disinfectants. In short, water is the most important thing, if you don't raise water well, it's useless to treat it.

Infection with fungus. The reason for this is due to the quality of the water, and adding some salt to the water can be a good way to prevent these fungal infections. It should be wiped with a diluted potassium permanganate solution, so that the disease will improve quickly.

It was its body that was inflamed and its tail was congested. The solution is to keep the temperature of the water at about 20 degrees. Add some medicine to give it **, and change the water more often in your daily life.

This belongs to the disease of rotten tailing.

Koi tail rotten disease may occur all year round, generally the tail fin scales fall off, inflammation, muscle necrosis, rot, the base of the tail fin is congested, the fin segment nucleus is opened into a broom shape, and in severe cases, the entire tail fin rots and so on. Even if such a koi fish is still strong and alive, it will reduce its ornamental value.

Unfinished ** Method reference: Put a gram of nitrofuracillin powder in 100 kg of water for washing and disinfection, and the condition can be relieved after multiple medications. Wash and disinfect with a low concentration of potassium permanganate solution.

The most important reason for the bad tail of koi fish is bacterial infection, generally and the breeding density is too large, the filtration function is not ideal, the water quality is too poor, there are new fish to join, the water quality is very different when changing the water, nervous or frightened, etc., causing the fish body discomfort, so that the surface mucosa secretion is abnormal, and the fin edge is infected because of weakness.

The possible reasons for turning black are as follows:

The koi are frightened and their tails turn black. The water quality is not up to standard, which leads to the blackening of the tail. Genetic instability leads to darkening of the tail.

It should be understood that raising koi fish needs to take the way of resting and recuperating, the color of the koi itself is unstable, and there will be great changes in the breeding process, and it may be normal for discoloration to occur. In addition, although koi fish can survive in water temperatures ranging from 0 to 35 degrees Celsius, they cannot withstand drastic temperature differences, which can cause stress reactions when the temperature difference exceeds 7 or 8 degrees Celsius, and problems such as dull body color, irregular dark spots, and death in severe cases.
