Why do koi prick the corner of the cylinder and how to deal with it

Too poor water quality: The angle of koi fish jar may be caused by too poor water quality, so it is necessary to change water and oxygenate the fish tank. Not adapted to the new environment: It may also be because they are not adapted to the new environment. At this time, they need to be put in a quiet place to rest for a period of time, and then they can recover after adapting to the environment. Scared: It may also be frightened. At this time, it needs to be fished out and put in a dark place for a period of time.

1. The water quality is too poor

1. Reason: If you don't change the water in the fish tank for a long time, feed too much or often don't clean the fish tank, the water quality in the fish tank will deteriorate and the dissolved oxygen content in the water will also decrease. At this time, there will be the phenomenon of koi pricking the corner of the cylinder.

2. Treatment method: Pour out the water in the fish tank and scrub the fish tank, then replace a quarter of the water in the fish tank, and ensure that the quality difference between the old and new water is not too great. Then, like oxygen in a fish tank, increase the amount of dissolved oxygen in the water.

2. Not adapted to the new environment

1. Reason: When koi fish is just changed or bought home, they will not adapt because of the great change of water quality, and at this time it will get together on the corner of the fish tank.

2. Treatment method: Before koi fish enters the new fish tank, the water in the original fish tank can be added to the new fish tank. If the new fish tank is too big, you need to add new water to it. However, it should be noted that the difference between fresh water and raw water should not be too big. Then put the new fish tank in a quiet place, and after they adapt to the new environment, they will swim everywhere.

3. Scared

1. Reason: When koi is mixed with other fierce fish, they will chase koi everywhere, or the surrounding environment is noisy. All these will scare koi, causing them to get together in the corner of the cylinder.

2. Treatment method: First, fish out koi fish and raise them separately to avoid being bullied. Then put koi in a dark and quiet place. In such a place, they will feel more secure.
