1. Water quality problem: When changing the water, the water temperature and PH value of the new water and the water in the original tank are quite different. The water quality changes, which stimulates the koi fish and causes floating. Culturists should pay attention to the PH value of the new water and the water in the original tank when changing water, and the water temperature of the new water can be 0.5-1 degrees higher than that of the original tank.
2. Feeding problem: If the koi is fed with floating feed for a long time or the feed particles are very small, the swim bladder tube of the fish will be blocked, causing the koi to float. Farmers must pay attention to keeping the freshness and safety of feed.
3. Bacteria problem: It is possible that the newly added fish or the fed live bait carry bacteria, which causes the koi to lose its float due to bacterial infection.
For the loss of floating fish, the breeder should fish out separately for treatment, soak in sodium chloride solution and stop eating and rest. In the course of treatment, water can be changed according to the situation. You can also feed the lost koi to eat cooked mung beans, one grain a day. The breeder also needs to add three thousandths of crude salt to the water in the original tank to sterilize and purify the water quality, and change the water in the later period, so as to ensure that other koi will not be infected by bacteria.
