This fish is covered in white substance, what s wrong?

There are white spots on the koi fish, which is caused by the koi fish suffering from white spot disease, and it needs to be carried out on the koi fish in time.

Symptoms of koi white spot disease:

Diseased koi fish are covered with white spots, in which they can be seen to breed white spot larvae, which attach themselves to the koi and grow exponentially. Koi fish rub against hard objects in the pool because of their itchy bodies, and koi fish are getting thinner and thinner, preferring to float on the surface of the water and move slowly. In the later stages of the disease, koi fish will have a white film on their bodies, secrete a lot of mucus, and their body surface will be dull.

White spot disease** method.

1. It is not easy to reproduce at a water temperature of more than 25 degrees, and it begins to die at 28 degrees), and it is prevented and controlled. After a few days, the cyst of the melon worm will gradually rupture and fall off, at this time, replace the new water, keep the water temperature constant, and the basic skills of the diseased fish will be cured. If supplemented with drugs, the rate can reach more than 90%.

2. Put nitrofuranacillin powder the size of soybean grains in the aquarium with a soluble water volume of 50 kg, dilute it and sprinkle it in the water to medicate the diseased fish.

3. Red potion**. The key to this method is not to add more, the water color has been reddish, rather less than more! Soak for 5 10 minutes, 1-2 times a day.

4. Put the sick fish in one percent salt water and take a medicated bath for 3-5 days. It is difficult to kill the adult insects of white spot disease, but it is easy to kill the larvae, so it can be completely extinguished by maintaining the effective agent in the water for about 7 20 days.

Injured, sick, bad water quality.

The fish may be a mold infection, it is recommended to change the water immediately, and then put a certain proportion of bath salt and compound zinc Luoning in the new water for disinfection. Then put the fish back into the tank.

Increase the water temperature and wash with 3% salt water.

There are many causes of the disease, such as water quality problems, wounds on the fish, and large temperature differences when changing the water.

When you get sick, the representative is dying. Fish without oxygen will be like this for several days, and it is generally difficult to feed fish without oxygen.

If you're sick, try some anti-inflammatory drugs.

Trying to change the water can sometimes be a problem with the water.

Just add a little salt to the fish tank, don't ask me how I know, because that's what my brother does.

It's a form of vitiligo, right? You can be like that creature. Animals and plants that kind of hospital to consult, there is an area. Drugs to remove vitiligo. You can kill in a fish tank. Or rub it on your body. Maybe it will be good.

I have white hair.

White hair disease, also known as water mold, is one of the most common diseases of ornamental fish.

Symptoms: The fish body is injured, or the parasite invades and destroys, the spores of the mold invade the wound, absorb nutrients, and grow rapidly, one end of the hyphium goes deep into the muscle, and one end grows outward, forming cotton wool-like hyphae. When mold is just parasitic, it is generally not easy to find; By the time it was discovered, the hyphae had invaded the wound on the fish's body and were growing from the outside to the inside.

The hyphae are entangled and adhered to the cells and tissues of the wound, causing tissue necrosis. Due to the increasing number of cotton wool-like mycelium, the fish body is overburdened, causing swimming disorders, loss of appetite, and becoming thinner and weaker, resulting in death.

Method: 1Mix 4/10,000 of salt and 4/10,000 of baking soda and sprinkle the whole tank or take a medicated bath.

2.Soak in 2 parts per million (2ppm) of potassium permanganate solution plus 1 table salt for 20 for 30 minutes.

3.Soak in 1 to 2 parts per million (1 2 ppm) of methylene blue solution or malachite green solution for 20-30 minutes.

4.。Installing a 15-watt UV lamp on the top of the aquarium for several hours a day can effectively inhibit or eliminate the growth of water mold.

Prevention method: A small amount of salt can be put in the aquarium to suppress water mold, and pay attention to cleaning and disinfection when putting live bait. The water quality must be kept clean to prevent the occurrence of water mold.

The presence of white flocculent on the fish indicates that they have white disease. The disease is usually more common in early spring and late winter, when the water temperature is below 20. Diseased fish develop white hyphae that grow more and more over time, causing them to swim erratically and lose their appetite.

If you want to **, you need to increase the water temperature to 30 and inject an appropriate amount of penicillin.

Also add a little coarse salt and change the water.

There are symptoms of wounds and water mold infection on the body. Most of those fish are hopeless. It is usually seen in the mouth of the pond where the disinfection of the fish fry is not complete when they go down to the pond, and the whole pond is not disinfected in time after the fry are put into the pond, and the water quality of the fish pond is relatively thin. General practice:

1. Fish fry should be disinfected with potassium permanganate, brine, thioetherfloxacin or iodine preparations before going to the pond;

2. After the fry are put into the pond, iodine preparation, or thioetherfloxacin, or salicylic acid or the latter two are mixed and sprinkled;

3. Fertilizer the water body of the fish pond in advance. The occurrence of water mold in fertilizer ponds is much better than that in thin ponds.

4. Strictly control the quality before purchasing fish fry. If there is obvious trauma or poor physique, do not purchase it directly, so as to reduce the risk of breeding from the source!

White spots on the fish are melon worm disease.

White spot disease is caused by a parasite called melon worm. The cause of this disease is mainly caused by the large temperature difference, and there will be a small number of sporadic white spots on the body of the diseased fish at the beginning, which generally do not break out in pieces, and the white spots are larger than those of powdering. The most important point is that the end of the fin of the diseased fish does not show redness and ulceration, and only in the later stage when it is severe will a large number of white spots erupt.

Melon insects are afraid of high temperatures, so heating up** is the best and easiest way to do it.

In the early stage, if there are not many fish suffering from white spots, we can also use a small soft brush to gently brush off the white spots of the diseased fish, and then cooperate with drugs such as heating, adding salt or adding white spots**.

Other susceptible diseases of fish:

Powdering is one of the most difficult diseases to distinguish from white spot disease, and its cause is mainly due to acidification of water and a large number of algae bursts, which are caused by an eosinophilic oodinoflagellates. In the early stages of the diseased fish, the mucus on the body will gradually increase, and some small white spots will appear at the end of each fin, and the white spots will increase very quickly, as if it is snowing.

This is followed by ulceration and redness at the ends of each fin, and these small white dots will increase in pieces on the body of the fish, as if a layer of powder is applied to the body of the fish, so it is called powdering disease.

Eosinophilic ocuflagellates like acidic water quality, which can be adjusted to a weak alkaline water quality by changing the water in large quantities, or using baking soda and pH test paper, and then combined with an appropriate amount of anti-inflammatory drugs to recuperate the disease.

White spots on the fish are melon worm disease.

The white spots on the fish are freshwater melon worms, which will cause the fish to die for a long time, and can be heated and the water temperature can be controlled above 30 degrees for 4-5 days, and the melon worms will automatically fall off and die.

There are small melon worms in the water, which is caused by the entry of germs and the low temperature of the water, so it is better to feed pellet feed instead.

Solutions to the problem of white spots and white hairs on the body of fish:

1. Put the fish tank indoors, or heat it properly, slowly, not too suddenly, otherwise the fish will not be able to stand it.

2. Put some mercurous nitrate in the water, which is sold in the fish market, about 2-3 yuan a bottle, and use it according to the instructions on the bottle. At the same time, you can put some yellow powder (fummicillin), the water will be a little yellow, it doesn't matter, use the medicine for three days, and then change one-fifth of the water every day until the water is not yellow. Frammicillin and mercurous nitrate can be mixed, nothing ***.

But please remember: frammicillin and high acid nails must not be mixed, there will be chemical reactions, and the water will be very turbid, so the yellow powder must not be put or brought in in the tank. Flocillin focuses on white disease, mercurous nitrate focuses on white spot disease, and high monocillic acid is used for disinfection.

If you use a high acid nail, you can only fish it out for a single use, and after use, you must use the water scooped out of the tank to pass it first (soak it) before you can fish it back into the original tank. The time of the turtle must be short, not more than two minutes, and the power of the drug is very great.

1) When changing the water, it should be noted that the temperature difference is too large, which will cause the fish body to "catch a cold" and let the pests and diseases take advantage of the weakness to invade the fish body.

2) Make full use of the weakness that the melon worm can die on its own after 24 hours if it cannot find a host, and the water for raising goldfish should be exposed to the sun or left to stand for 2-3 days before use. This is one of the best ways to prevent melonworm disease.

3) according to the proportion of grams of mercury nitrate per cubic meter of water for the whole pool (tank) or when the water temperature is below 15, you can put grams of mercurous nitrate in 50 kg of water, bathe the sick fish for about l hours, and then wash with isothermal new water, and then put back into the sterilized new pool (tank), and rest after adding a little green water. However, it should be noted that mercurous nitrate is highly toxic and should be used with caution. In particular, the resistance of small fish to the liquid medicine is weaker than that of large goldfish, so the concentration of the liquid medicine should be appropriately reduced, and the immersion time should be appropriately shortened.

4) Put 10 kg of red mercury (i.e. medical red syrup) ml, bathe the sick fish for 5-15 minutes. If it is color, it can be directly rubbed with red mercury on the part or around the body. After washing with fresh water, and then put it into clean new water to raise, you can also splash 3-5 (g) ml of red mercury according to l cubic meters of water (i.e. l000 kg) to make the pool (tank) water concentration of 3-5 mg liters.

After 2-3 days, depending on the condition of the condition, you can change to the above bathing method** once, and then change to clean new water (tender green water) to feed, and at the same time extend the sunshine time, appropriately increase the water temperature, stop eating, and increase oxygen, and you can obtain satisfactory results.

5) According to the characteristics of small melon insects that are not resistant to high temperatures, put them in the sun, raise the water temperature to 30 hours, rub red mercury around the body of the fish, and then wash them with new water and then clean them in warm and tender green water to raise, stop eating, and change to new water after 1 week in the sun.

6) In the range of water temperature 20-26, each cubic meter of water (1000 kg) baths the diseased fish with grams or grams of malachite green solution for 2 hours, which can kill small melon worms and is relatively safe for goldfish.
