The goldfish is rotten, and the goldfish at home has rotten meat, what should I do?

Judging from your description, the disease that your small fish suffered from at the beginning may be white spot disease, and there are many causes of white spot disease, the main reason may be that the water quality is not clean and there are a large number of bacteria, or the small goldfish has been in water with different water temperature before the onset of the disease, and the large water temperature difference is also one of the causes of white spot disease in the fish. In the initial stage, you can use white dot agent (where you sell fish)**, but the water temperature must reach 27 to 28 degrees for the obvious effect. Now look at your little fish must be inflamed because of bacterial infection, you have to use gentamicin sulfate**, plus all-purpose fish medicine (this must be an ace or a fish treasure brand to have obvious effects)**, change one-half of the water every day.

Keep the water clean, and insist on replacing the medicine with a new one, and the fish will be fine. A box of ten gentamicin sulfate costs 5 yuan, and the all-purpose fish medicine costs about 15 yuan, but both of these can be used for a long time. I hope your little fish hurry up**.

Attention should be paid to the cleanliness of the pool water to avoid the invasion of parasites, and the careful operation should not injure the fish, which can reduce the occurrence of this disease. The following drugs and methods** have satisfactory results. 1. Topical drugs are the same as bacterial gill rot.

2 Injection of chlortetracycline at 5 000 units per kilogram of fish body weight. 3 Tetracycline ointment is applied to the affected area.

Suggestion: Remove and soak potassium permanganate for 24 hours.

This disease will be contagious between fish, when changing the water, you should put some edible salt into the water to kill the effect, you are too careless, the salt should be moderate, less does not work, more is not good for the fish, according to the amount of water, according to the amount of 3 liters of 1 spoon added, this spoon is a small spoon, after changing the water, you can add it. If I do what I say, it won't take more than three days of fish with mild symptoms. But if it is serious, it will take about a week, and the way to prevent this disease is to add a little salt every time you change the water to prevent the water from deteriorating faster.

Change the water every week. If the weather is hot, it should be held every three to five days. It depends on the quality of the water.

When I say salt, I mean edible salt and it works. My fish are so good.

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 ?

White spot medicated bath: The rotten body of the goldfish may be due to white spot disease, and the symptoms of ulceration of the fish body will appear in the middle and late stages of this disease. If the goldfish is found to have festered, the keeper will need to use a white spot medicated bath**.

Malachite Green Medicated Bath: Goldfish suffer from water mildew, and the fish body will also fester, and the keeper will need to use the Malachite Green Medicated Bath**. Oxytetracycline medicated bath:

It is also possible that the goldfish is rotten because of rotten fins, and at this time it is necessary to use oxytetracycline medicated bath**. <

1. Reason: Goldfish may have white spot disease if it is rotten, because when the symptoms of white spot disease are more serious, the fish body will ulcerate. White spot disease is mainly caused by low water temperature or too large temperature difference, and small melon insects have an environment to reproduce.

2. Method: If the body of the goldfish has been ulcerated, it means that the symptoms of white spot disease have been more serious. At this time, the keeper needs to raise the water temperature to 25-28 first, and then use the white spot net for a medicated bath, about 15 minutes a day, and insist on improving for a week.

1. Reason: The ulceration on the goldfish may also be caused by water mold, which is mainly caused by the invasion of mold spores caused by external injury. In the early stage of water mold disease, white flocculent matter will appear on the diseased part, ulceration will appear in the middle stage**, and ulceration will become larger and larger in the later stage.

2. **Method: Breeders can use malachite green medicinal bath first, and if the symptoms are more serious, they can be matched with methyl blue. Generally, 100 kg of water is put in malachite green or methyl blue, and the diseased fish are medicated for bathing, and the medicated bath is 10-20 minutes a day, and the mycelium will fall off on its own after a few days.

1. Reason: It is also possible that the goldfish is rotten, mainly caused by poor water quality. Rotten fin disease usually occurs in the fin area of the fish, and only spreads to the fish when the symptoms are more severe.

2. ** method: the keeper can first use salt water to clean the diseased fish, or use oxytetracycline to give the diseased fish a medicated bath, and can also soak the diseased goldfish with a low concentration of potassium permanganate.

Maybe it's because of rotten fins.

Solution: Once this situation is discovered, it must be isolated immediately, and then antibiotics or drugs such as tintle yellow must be applied to ** the diseased fish. If the symptoms of rot are slow, the best way to do this is to replace some of the water in the tank, clean the filter and add a little salt to the tank, and stop feeding for a few days.

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: When the goldfish is infected by the invasion of the sail removal 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 hail and rainy season, a small amount of salt can be put into the fish pond to have a preventive effect.
