Causes of Koi Weakness and Prevention and Treatment of fin and tail rot disease

Treatment must first begin with confirming the disease, sokoifin and tail rot during the onset period show these symptoms: first, the edges of the fins show a slight opaque appearance, then the membrane continuously peels off, exposing the fin rays, and the fin rays split one after another; if left untreated, it will cause thekoi fish's death.

Treatment methods

a. Put 0.2 g of nitrofurazone powder in 100 kg of water for soaking disinfection; after repeated medication, the condition can be relieved.

b. Put 3-5 tablets of furazolidone in 100 kg of water and soak the diseased fish for 30 minutes.

c. Put 5-8 tablets of oxytetracycline in 100 kg of water for soaking disinfection, which can prevent infection with this disease.

d. Soak and disinfect with a low-concentration potassium permanganate solution.

e. Soak with gentamicin; in a 100 cm x 50 cm x 35 cmaquariumput 2 tubes.

To deal with tail rot, if fish medicine cannot be found for the moment, you can buy Xieliting (furacilinone) at a pharmacy, find a small tank for a medicinal bath, add 8 tablets to a 40CM tank (slowly rub them to dissolve in water), and aerate at the same time. If they are tropical fish, raise the water temperature to 30°C and add half a tablet every other day; the effect is excellent. Generally, they will recover within a week.

Also, for mild koi gill rot and fin rot, adding a large amount of salt can have an effect of relieving the condition, but once it becomes slightly more serious, professional medicine must be used for treatment to prevent the condition from spreading and worsening.

For relatively serious fin and tail rot, the incomplete and uneven parts should first be cut off with scissors to make them smooth, and then the above treatment methods should be used for treatment.
