Rotten fins and tails are very harmful diseases, and they will also infect water quality. If the sick fish are not salvaged in time, the fish will infect each other. The main reason for rotten fins and rotten tails is that the water quality in the fish tank is too acid or too hard, which leads to a large number of bacteria breeding and infects the fish. Breeders do not pay attention to changing water for a long time, which will also lead to too many impurities in the water, causing water mold to breed in the water. Another reason is that the water quality environment of fish tanks has changed strongly, which will lead to their inability to adapt to the environment and the problem of rotten fins and tails.

There are several methods to treat the rotten fins and tails of guppy fish:

1. Put 0.2 g of furacilin powder into 100 kg of water for soaking and disinfection, which can relieve the disease after several times.

2, put 3-5 tablets of furazole in 100 kg water, and soak the sick fish for 30 minutes.

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

4. Use low concentration potassium permanganate and salt solution for soaking and disinfection.

5, soak the diseased fish in 1% salt water until the fish recover.

Broom-type unfinished tail begins to fester from the middle of the tail and spreads rapidly to the tail. The onset time of both sides of the caudal fin is after the middle, sometimes the dorsal fin also develops, and later spreads from the caudal fin to the caudal handle. However, the disease develops so rapidly that it will die after being treated later. If you are treated with drugs, you must prescribe drugs according to the instructions, and do not overdose them. They can be cured in the early stage, but there is basically no effect in the late stage.
