What s going on with the rot on a goldfish?

1. First of all, isolate the sick fish to prevent cross-infection with other healthy goldfish, prepare a new container, draw out the raw water from the fish tank and inject it into the new container, 1% sea salt + yellow powder poured into the raw water to do a medicinal bath, yellow powder (nitrofuracilin) is my favorite drug, mild and effective, add to the water slightly yellow, the dosage gradually increases from less, so that the small fish can slowly adapt, you can also use a cotton swab dipped in yellow powder directly to apply the affected area, the effect is better, each medicated bath time is about 20 minutes, the course of treatment is 3-5 days;

2. If the effect of yellow powder is not obvious, you can consider choosing potassium permanganate and malachite green, but these two are definitely fierce drugs, and the dosage must be used carefully, and it is more safe to use half of the dosage according to the instructions, otherwise the small fish will be very unbearable.

Once the goldfish is found to be ill, it should be isolated in time, otherwise the condition will be life-threatening if it is serious, and even if it is cured, it will leave scars and affect the ornamentality.

The goldfish at home has rotten flesh is skin mold, when the mycelium is thick and dense, the fish body is overburdened, swims slowly, loses appetite, and eventually dies, and sometimes the hyphae are congested or ulcerated in the wound. Here's how:

1. Strengthen feeding management to avoid fish injury. Prior to overwintering, the disease can be effectively prevented by drug treatment to kill the parasite based on the results of a microscopic biopsy.

2. Use malachite green concentration aqueous solution to apply wounds and water mold lesions.

3. Soak with malachite green 1:15000 concentration for 3-5 minutes.

4. Sprinkle the whole pool with a mixture of 400ppm-500ppm salt and 400ppm-500ppm sodium bicarbonate. Due to the large amount of pesticides, the diseased fish are usually concentrated in small cement ponds for pesticide application.

5. Taken internally with vitamin E, the dosage is exactly the same as that for the prevention and treatment of erect squamous disease.

6. Create external conditions conducive to the hatching of fish eggs (pay attention to water temperature and density of fish eggs), and soak fish eggs (together with fish nests) with 1:15000 concentration of peacock green for 10-15 minutes to prevent fish eggs and water mold.

Causes of water mildew:

The occurrence of water mold disease is mainly due to the urgency of the secondary infection, the fish only due to crowding, movement or other adverse environmental factors, resulting in body surface tissue injury, water mold spores are waiting for the opportunity to attach, on the necrotic tissue began to germinate to form hyphae, in addition to parasitic in the necrotic tissue, the hyphae can also spread to invade the nearby normal tissues, secrete digestive enzymes to decompose the surrounding tissues, and penetrate through the dermis deep into the muscles, so that the first and muscle necrosis disintegrate.

The mycelium on the surface extends outwards to form a cotton wool-like covering, and at the end it forms a sporangia that release free spores into the water and spread through the water.

The operating procedure of the sick fish ** is as follows:

1. Use a fishing net to fish out the affected fish, and grasp it with your hands (remember, you must hold on, that little thing is very strong).

2. Dip a cotton swab in potassium permanganate solution, wipe the affected area, and wipe off the rotten meat with a little force.

3. Change the cotton swab, dip it in iodine wine, and wipe the affected area.

4. Change the cotton swab, apply erythromycin eye ointment, wipe the affected area, erythromycin eye ointment mainly plays a covering role, and prevents germs from re-invading the fish body.

5. Put the sick fish in the water. If there are other diseased fish, please repeat the above operation.

Precautions: Due to the use of high concentration of potassium permanganate, this substance has a super oxidation ability, so do not dip too much on the cotton swab to prevent it from flowing into the gills. I accidentally leaked potassium permanganate into the gills of the fish during the ** process, causing it to die.

The operation of two people, one person catches the fish and applies the medicine, and the other person dips the medicine to deliver it, which will greatly improve the efficiency, and can effectively control the amount of medicine, and prevent the occurrence of unpredictable accidents such as rushing to overturn the medicine (again, potassium permanganate is a strong oxidant, where it flows, which yellow piece). **, the height of the fish from the ground should be lowered as much as possible, and it is better to place a basin below, so as not to break free of the fish, not cured, and fall to death.

Hurry up and pick up the red potion·· Keep the water clean·· It's best to keep it alone... Coarse salt in the water prevents other fish from spreading bacteria and prevents bacterial infection. Destruction of water quality.

Rub the red potion, rinse with water, and put back the coarse salt under the original jar.

Rotten ends, white spots, ** is very simple, don't be afraid!

What should I do if the fish has rotten mouths and rotten eyes? What medicine is used ?

Salt water, potassium permanganate: The rotten body of the goldfish may be due to water mold, the fish body has a wound, and the water quality is corrupted, causing water mold. The fish can be soaked in 1% brine plus 2 ppm potassium permanganate**.

Chlortetracycline, ?Oxytetracycline: It may also be caused by tail rot and fin rot, mainly caused by poor water quality.

Chlortetracycline or oxytetracycline can be used**. Yellow powder: It may also be a bruise, the wound is infected, at this time, you can use a yellow powder medicated bath**.

1. Reason: The body of the goldfish is scratched when it is transported or changed to water, and it loses its protective properties to the body. In addition, the water quality is relatively poor at this time, and the mold in the water will continue to spread on it, causing water mold disease.

Usually the light is insufficient, and it cannot be sterilized, and the condition of water mold disease is aggravated, and the body will ulcerate.

2. What medicine is good to use: use 1% brine with potassium permanganate of 2 parts per million to make a solution, and let the sick fish soak in the medicine for 20-30 minutes. After 3 days of continuous medication and ultraviolet radiation, the ulcerated wound will slowly scab over.

1. Reason: Goldfish suffer from rotten tail and rotten fins, and the water is in a turbid state for a long time, and bacteria will breed in the water. When the goldfish is a little weak, bacteria will easily invade the fish's body, and the fish will fester.

2. What is the best medicine to use: it is best to mix chlortetracycline or oxytetracycline with water**, put 5-8 tablets of medicine in 100 kg of water, soak the diseased fish for 20-30 minutes, and generally insist on taking a medicinal bath for three days.

1. Reason: I didn't pay attention to the goldfish when I fished, I hit the fish body when I changed the water, and the fish was bitten when I was fighting. If you don't notice the wound and don't treat it in time, the wound will become infected and the body will ulcerate.

2. What is the best medicine to use: You can use yellow powder medicated bath, or you can apply yellow powder to the location of the goldfish wound.

Goldfish ** festering, this rot disease is caused by mold, mainly caused by deterioration of water quality and lack of oxygen. In the early stage of this disease, it is water mold disease, and there is white mold attached to the body of the fish in the disease, and later as the disease worsens, it becomes a rot disease, which can rot both fins and heads. Conservation management should be good in the circulatory system, which can not only improve the water quality, but also oxygenation, especially when the water temperature is low, it is more likely to occur this disease, but generally this disease can be prevented after soaking with a slightly higher concentration of salt water in the initial stage, if your fish has been more seriously ill, it should be immediately soaked in malachite green solution, and there is a description on the measuring bottle, and potassium permanganate can also be used, once a day, until it is cured.

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. When X0D X0A ornamental fish are infected with mold, they are also affected by the length of time they are exposed to light.

Prolonged periods of rain or lack of indoor lighting, daylight, etc., can all contribute to the growth of mold. The body of the fish infected by mold is usually covered with a layer of white pannus, especially the black and red fish are the most obvious, thus losing the luster of the fish body. Subsequent sluggishness, often sluggish, floating on the surface of the water, if not timed**, the fish body mold spreads, the affected muscles rot, loss of appetite, and eventually lead to death.

X0D X0A can also be used to increase the water temperature to inhibit the growth of water mold. 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.

The rot on the goldfish is due to the fact that the goldfish has water mold.

The cause of water mold disease: a fish disease in which water mold and cotton mold invade after the trauma of goldfish** and parasitize on the fin wounds or corrupted eggs of the fish.

Symptoms of water mold disease: When the goldfish is infected by the invasion of water mold, the skin tissue ulcers, mucus increases, and gray-white mycelium appears, this mycelium parasitizes the affected part of the fish, and gradually extends into the muscles, absorbing the nutrients in the fish body to nourish itself, so that the diseased fish gradually appear restless or lazy swimming and loss of appetite, and finally weakened and died.

Prevention and control methods: In the disease season, especially in the mildew rainy season, a trace amount of salt can be put into the fish pond to have a preventive effect.
