CATDOLL : CATDOLL: The goldfish are bleeding all over and have turned red. Several of them have died. What should I do?

1. The goldfish are bleeding all over and have turned red. Several of them have died. What should I do?

The above is nonsense! This is a viral disease, spring sickness virus. It is estimated that most of them are dead by now. Hurry up and heat it up! Heat it to above 24℃, and remove all dead fish, and change 1/2 of the water! Stop feeding. This may be caused by feed and water quality. The water should be dried for 3 days. If possible, try using viral interferon.

2. What is the disease of congestion and ulceration of the goldfish's tail?

Yellow powder and coarse salt are used together mainly for bacterial infection

In severe cases, you can add 2 bottles of gentamicin and 2 bottles of water in a basin to take a dark bath.

Yellow powder and coarse salt can be used for continuous medicinal baths

3-5 days

The concentration of yellow powder should not be too high. Just add it until the water changes color. The concentration of crude salt should not exceed 0.8%.

After taking a gentamicin bath for one hour, put it in the yellow powder tank and continue taking a gentamicin bath to suppress the further development of the disease.

The basin for medicinal bath should not be too small. It is best to add an air head to prevent lack of oxygen. The air volume of the air head should be small so as not to affect the rest of the goldfish.

3. What should I do if my white goldfish becomes red and its scales stand up?

Don't be afraid, this is explosive scale disease. It will be cured if treated in time. The scale disease is vertical scale disease - also known as standing scale disease, pine scale disease, pine bark disease, etc.

[Symptoms] The symptoms of the diseased fish are characterized by a rough body surface, and most of the scales at the tail are spread out like pine cones, while the scale sac at the base of the scale is edematous, and translucent or bloody exudate accumulates inside, causing the scales to stand up. When a little pressure is applied to the scales, the liquid will spray out from the scale sac, and the scales will fall off, sometimes accompanied by congestion of the fin base and skin surface, protruding eyes, and swollen abdomen. The diseased fish swims slowly, has difficulty breathing, turns sideways, and the abdomen is upward, and dies after 2 to 3 days. The disease is easy to occur when the water quality is not clean, the light is insufficient, the water is lacking oxygen, the water temperature is too high, and when the scales of the fish are scratched. Goldfish and koi often suffer from this disease, which is more prevalent in spring every year. Among tropical ornamental fish, foam-oviparous fish such as the Percichthyidae, Bettas, and Killifish often suffer from this disease. This disease is difficult to cure. Even after recovery, the color, luster, and body shape are not as good as before.

[Treatment method] The sick fish can be immersed in a tetracycline solution with a concentration of 1/50,000 unit for 1 hour; it can also be bathed in a mixture of 2% sodium chloride solution and 3% sodium bicarbonate solution for 10 minutes; or it can be immersed in chloramphenicol solution, or furacillin powder plus sulfamethoxazole solution, or gentamicin solution. It can also be diluted with 1% of the above liquid into a low dose for spraying. It will be effective if it is persisted for several days.

4. What is the reason for the red blood on the goldfish?

The symptoms on the goldfish are called erythema. This is a disease caused by water pollution, the bottom sand has not been washed for too long, or the water has not been changed for too long. Because goldfish eat dorado, it causes a lot of water pollution. If the filtration system itself is not good, it is very common to suffer from this disease. Erythema is an inflammation or ulcer of the epidermis. It is a bacterial infection disease. It is usually infected by Pseudomonas erythematosus, Haemophilus ichthyophilus, Vibrio ichthyophilus, Aeromonas, and Columnar Myxomycetes. When the waste in the water accumulates to a high level, the natural defense of healthy fish to inhibit bacterial infection will be destroyed. At this time, many small red spots will appear on the fish body in the early stage. If they are not treated, they will expand into red patches, similar to subcutaneous hemorrhage. In more serious cases, the skin will break and bleed. The location of the erythema may be part of the body. It is also possible that the skin of the whole body or under the skin will be red. Sometimes there will be local suppuration or ascites on the side of the body. In the early stage of the disease, the fish's behavior still looks very normal. However, if it is not treated quickly, the erythema will spread quickly and may cause the death of the fish. In severe cases, the capillaries of the whole body will be congested or bleeding, and it will look bloody. The best treatment is to change a lot of water and clean the bottom sand and filter in the early stage of the disease. Usually, it can be cured without medicine. But in more serious cases, the sick fish will be isolated and bathed in yellow powder medicine to recover. Usually, adding some coarse salt to the water when changing water is the main prevention.

5. Urgent! High score! ! My goldfish suddenly developed blood spots. One of them died (sad). Please help me, experts! ! ! Thank you

If you have kept it for several years, it should be quite big. As time goes by, you will develop some feelings for the fish.

Goldfish suddenly develops blood spots: the reasons are as follows

One possibility is that the goldfish may have lost some phosphorus and the water quality has deteriorated, leading to infection!

The filtration system in the fish tank can work normally, such as the water pump and the thermostat, which will cause hypoxia and abnormal water temperature and affect the fish.

3. The fish have not been fed recently, so they bump around in the fish tank. After the fish are injured, bacteria infection

Feeding too much fish food, not finishing the food, and not cleaning it up in time will affect the water quality of the fish tank.

5. The fish tank may not be cleaned, disinfected, or water changed for a long time.

The best solution now is: if you are raising tropical fish, you must leave one-third of water in the fish tank when changing water.

Change the water immediately. Take the fish out of the fish tank and disinfect it with digestive bacteria, baking soda, sea salt, gold drops, potassium permanganate, etc.

Please ask a professional to clean the fish tank thoroughly.
