If the fins are rotten, they can heal themselves. If you want it to recover, you must first stop feeding, which can reduce the content of organic matter in the water and slow down the reproduction speed of bacteria. After that, it needs to change water, heat up and salt. Generally, the water is changed once a day or two, one quarter of each time. The water temperature rises by 1-2 ℃, and the salt concentration is between 0.3-0.5%. If this is not cured, it needs to be soaked with medicine. 1、 Can it heal itself? The rotten fin can heal itself. However, the self-healing here does not mean that it depends entirely on itself. It still needs some help. It needs to change the water frequently, increase the temperature appropriately, and add salt and oxygen explosion at the same time. It should be noted that the effect should be effective only when the condition is mild. If the condition is serious, it must be treated with drugs. 2、 Treatment 1. Stop feeding: after finding that the fish has rotten fins, the first thing to do is to stop feeding. Because the fish do not have a strong appetite when they are ill, and there is not much to feed at this time. After the remaining residual bait is decomposed, it will accelerate the deterioration of water quality, which is very unfavorable to the recovery of fish. Moreover, fish are relatively hungry, and there will be no problem if they are not fed for a few weeks.
2. Old three: in order to help the fish heal better, we need to change the water and heat up the salt. Change the water frequently, every other day, about a quarter of each time. After changing the water, raise the temperature appropriately and increase it by 1-2 ℃ compared with the original, but not too high. Then put salt into the water with a salinity of 0.3% - 0.5%. After changing the water, add salt in proportion.
3. Medicine bath: it is unrealistic to rely on self-healing in the later stage of rotten fin. It still needs to be treated with drug immersion. You can mix 0.2g of furacilin powder with 100kg of water to form a solution, and immerse the fish in it. You can also add 3-5 tablets of dysteryl or 5-8 tablets of oxytetracycline in the same amount of water. (YuQiLanLeNengZiYuMa,ReDaiYuLanQiLanWeiZenMeZhi)
