Why do brocade carp jump in the middle of the night, how to deal with

Insufficient dissolved oxygen in water: At this time, an oxygen pump needs to be put in the fish tank to continuously hit oxygen in the fish tank. Adequate oxygen will keep their metabolism stable. Scared: At this time, koi fish should be fished out and kept in a quiet place. Infected with parasites: At this time, koi fish should be fished out and their body surface should be sterilized with a certain concentration of potassium permanganate. Then replace the water in the original fish tank with new water, and then put the sick fish back for conservation.

1. The dissolved oxygen in water is insufficient

1. Reason: At night, plants in water will breathe and consume oxygen in water. When the oxygen content in the water is insufficient, it will cause koi fish to have difficulty breathing. At this time, they will want to jump out of the fish tank and breathe oxygen.

2. Treatment method: Reduce the amount of aquatic plants appropriately to avoid them competing with koi for oxygen at night. Add an oxygen pump to the water, and turn on the oxygen pump at night to increase the content of dissolved oxygen in the water and avoid koi jumping.

2. Be frightened

1. Reason: If the sound outside is very loud at night, it will wake them up, and at this time they will instinctively jump out of the fish tank.

2. Treatment: Fish out the frightened koi and keep them in a quiet place. Be careful not to feed them during feeding, so as to avoid scaring them again. After they recover, they can be raised normally.

3. Infect parasites

1. Reason: Koi is easily infected by parasites, and when they are infected with parasites, they will be restless. And will jump out of the fish tank.

2. Treatment method: Fish out koi infected with parasites, and smear potassium permanganate solution with a certain concentration on them to kill parasites and prevent them from infecting other fish. Then replace part of the water in the fish tank, and add a certain amount of crude salt to the water to reduce the content of parasites in the water.
