Koi tail hyperemia is what reason, how to treat?

Koi tail congestion may be caused by the collision of the tail on a hard object. At this time, it is necessary to remove the hard objects in the fish tank and disinfect the congestion. Or it could be an infection. At this time, it needs to be fished out and soaked in potassium permanganate for one minute, and then it can be maintained normally. It could also be a stress reaction. At this time, we need to adjust the feeding environment and light, and wait for it to recover.

1. Hard object collision

1. Reason: The body of Koi is relatively fragile. If it collides with a hard object carelessly, it will cause local congestion.

2. Treatment method: Fish out the koi and disinfect the congested part. In addition, we need to change the water again, and then put the koi into the fish tank for normal maintenance.

2. Infected bacteria

1. Reason: If there is a wound on the body of the koi, the bacteria will enter the body of the koi through the wound, and the tail will be congested.

2. Treatment method: At this time, it is necessary to fish out the koi, soak them in the diluted potassium permanganate solution for one minute, and then put them into the fish tank with changed water for maintenance. Can also be put into an aqueous solution adde with salt and vitamin C for maintenance, and can be cured in one week.

3. Stress reaction

1. Reason: If there is a sudden big change in the environment where the koi are maintained, for example, from a very quiet place to a very noisy place, and then from a dimly lit place to a strongly lit place, the koi will have a bloodshot tail.

2. Treatment method: At this time, it is necessary to immediately adjust the environment to the previous environment, or reduce the stress response of the koi. It can also be alleviated by slowing down the speed of running water, reducing temperature changes and reducing noise.
