with red blood in the tail of Koi 1. If there is a small amount of red blood in the tail of Koi, it may stimulate them when changing water, causing them to have a stress reaction. This condition generally does not require treatment, just turn up the oxygen in the fish tank.
2. If their tails have a lot of red blood, they may be infected with bacteria and parasites. The symptoms of these two conditions are very similar, and it is difficult to judge which one, so both conditions need to be taken into account. The tail of the diseased fish can be smeared with mercurochrome or other anti-inflammatory drugs. Then take the water in the original fish tank, add yellow powder and trichlorfon, and make a medicinal bath for the koi for about 20 minutes. Finally, prepare a new fish tank, and put the sick fish in it after the clear water. Take a medicated bath once a day in the morning and evening, and you will recover in about a week.
to put salt in the tail of Koi with blood? It is not allowed to put salt in the tail of Koi with blood, because salt contains iodine, which will affect the health of Koi. If you put salt, you'd better put sea salt or coarse salt, because sea salt and coarse salt can reduce water infiltration into the body, enhance immunity, and have a certain effect of sterilization and disinfection, which can promote the recovery of Koi.
