What happened to the goldfish falling off its scales?

Goldfish falling scales is a common disease of goldfish, that is, vertical scale disease, also known as standing scale disease, pine scale disease, and so on, which is mainly caused by a kind of Trichoderma punctata infection, which is more easily caused by low water temperature or excessive difference in water temperature in winter. Goldfish scales must be treated in time. Let's take a look at how goldfish scales fall.

Symptoms of vertical scale disease in goldfish

The body surface of goldfish with vertical scale disease is mostly rough, and most of the scales in the tail open outward like pine balls, while the scales at the base of the scales are swollen, exerting a little pressure on the fish, there will be translucent or blood-containing fluid flowing out. In addition, the scales of the goldfish will stand up, and serious diseases make it difficult for the goldfish to breathe and swim slowly. if the situation is serious, the goldfish will die within 2 to 3 days.

Causes of vertical scale disease in goldfish

The vertical scale disease of goldfish is mainly caused by bacteria, which are caused by bacteria such as Trichoderma punctatus, Pseudomonas hydrophila, Aeromonas hydrophila and so on. In the season of low water temperature, especially after overwintering, the fish have poor physique, weak resistance and easy to get sick. In addition, after the injury, it is easy to part of the scale, the frequency of water change should not be too large.

What if the goldfish falls off the scales?

1. Wash the fish with furacilin or furazolidone at a concentration of 20 mg / kg, 20 minutes at water temperature below 20 degrees Celsius, and 10 minutes at 21 degrees 32 degrees for prevention and early treatment.

2. When the concentration of furacilin or furazolidone is 0.2mg / kg and 0.3mg / kg, the concentration of furazolidone can be increased to 0.5mg / kg and 1.2mg / kg, which can be used for prevention and early treatment.

3. Wash the fish with the concentration of erythromycin 2-2.5 mg / kg, the water temperature is below 34 degrees, and wash for 30-50 minutes, once a day for 3-5 days until the condition improves.

4. Injection of streptomycin or kanamycin, 120000-150000 IU per kilogram of fish weight, usually only once, and second injection on the fifth day if the disease is serious.

5. Take norfloxacin (norfloxacin) orally, 0.8-1.0 grams of powder for every 10 kg of fish weight per day, once a day for six consecutive days.

6. Wash with 20 mg / kg rivanol for 15 minutes at 5: 20 degrees and 10 minutes at 21 degrees 32 degrees. The effect of early treatment is remarkable.

7. There is a special effect when the concentration of rivanol is 0.8-1.5 mg / kg.

Note: fighting between goldfish and companions can also cause fish scales, and collision scratching will also cause beautiful goldfish to fall off scales, because they inevitably collide with each other during transportation and cause damage to the body surface of goldfish during salvage.
