The rotten fins of map fish may be due to the poor water quality, which can eat and pull, and seriously pollute the water quality. If you don't change the water in time when raising at ordinary times, it is easy to breed bacteria and lead to rotten fins.

It is also possible that the fins of map fish are rotten because they are not treated in time after trauma. The fins of map fish are relatively fragile. Once there is a fight or collision, it is very likely that the fins will be injured. If the fins of map fish are not treated in time after being injured, they will rot.

If the rotten fins of map fish are not serious, they can choose to heal themselves. Breeders can transfer them to a separate fish tank first, then ensure the stable water temperature and water quality, and wait for them to recover by themselves. You can also add some crude salt or sea salt to the water to prevent bacterial re-infection.

If the rotten fins of map fish are serious, they still need to be treated with drugs. Breeders should first fish them out and treat them separately. The second is to sprinkle furacilin or furazolidone in the water where they live, and finally change the water and add medicine every day, and stick to it for about a week, and the rotten fins can be recovered.

In the future feeding process, it is necessary to minimize their fighting, and pay attention not to accidentally hurt their fins when fishing. If conditions permit, a circulating filtration system can be installed to ensure clean water quality.
