of raising koi fish to change water too frequently, if the koi fish change water too frequently, the fish will be stimulated by the new water, and even produce some stress reactions, such as body surface congestion, fin rot, and even fried scales. Moreover, frequent water changes will destroy the original ecological balance in the tank, leading to the death of nitrifying bacteria, once this happens, the health of fish will be threatened, or even die. In the daily feeding process, the change of water is generally controlled once every seven days.
1. Change water regularly: First of all, we should pay attention to changing water when raising koi. This kind of fish has a close relationship with carp, and has relatively broad requirements for water quality. However, changing water regularly to maintain water quality can also reduce the possibility of fish getting sick. Usually, it should be changed every five to seven days, and each change should not exceed one third of the total amount of water.
2. Pay attention to oxygenation: Koi is a large ornamental fish. It consumes more oxygen because of its large size. It must pay attention to oxygenation. In the daily feeding process, it is best to use an oxygen pump to oxygenate 24 hours a day and at night, so as to prevent the fish from floating.
3, proper feeding: fish digestion is relatively fast, so feeding is almost not enough, how much will eat, but this is harmful to the health of fish, it is easy to get enteritis and other diseases, and a large number of residual bait falling in the water, will also pollute the water, causing fish disease.
