The main reasons why koi don't compete for food are as follows:
Unsuitable water temperature: The optimal water temperature for koi is between 20°C and 28°C. When the water temperature is too high or too low, the feeding amount of koi will decrease. A drastic fluctuation in water temperature can cause koi to stop feeding. Therefore, maintaining stable water temperature is crucial.
Lack of oxygen in the water body: Koi have poor tolerance to oxygen deficiency, especially when they are raised in a small environment, they need to be supplied with oxygen 24 hours a day. Changes in temperature and air pressure may also lead to oxygen deficiency. It is necessary to observe carefully and supply oxygen in a timely manner at ordinary times.
Poor water quality: Poor water quality can cause koi to refuse to eat. Especially when the water body ages, even if the water quality parameters are normal, koi may still show a refusal to eat. It is recommended to change 1/8 to 1/10 of the total water volume of the fish pond every day for 3 to 5 days, and ensure that the new water has been dechlorinated.
Indigestion: Overfeeding can lead to indigestion in koi, and then they will refuse to eat. At this time, the feeding amount should be reduced, avoid feeding too much at one time, and try to add new water or increase the water temperature to stimulate digestion.
Disease problems: Koi infected with parasites or suffering from diseases such as saprolegniasis will experience a loss of appetite. At this time, the water temperature can be raised above 28°C, and antibacterial and anti-parasite drugs can be used for treatment.
Adaptation to a new environment: When new koi arrive at home, they need to adapt to the new environment. They may temporarily lose their appetite due to fear or nervousness. At this time, patience is required. Don't rush to feed them. Wait until they adapt to the new environment before feeding.
Overfeeding: Frequent feeding can lead to a large amount of food remaining at the bottom of the water, and the water body will become eutrophic. When koi are in a full state, they have no sense of hunger, so they don't like to eat. Feed in an appropriate amount and keep the water quality clean.
The methods to solve the problem of koi not competing for food include:
Maintain stable water temperature: Avoid drastic fluctuations in water temperature and ensure that the water temperature is between 20°C and 28°C.
Supply oxygen in a timely manner: Ensure that there is sufficient oxygen in the water body, especially when raising koi in a small environment, 24-hour oxygen supply is required.
Improve water quality: Regularly change the water quality to ensure that the water is clean and free of chlorine.
Feed in an appropriate amount: Avoid overfeeding, maintain an appropriate feeding amount, and prevent the water body from becoming eutrophic.
Treat diseases: If koi are sick, use antibacterial and anti-parasite drugs for treatment in a timely manner.
Be patient: When new koi arrive at home, be patient and wait until they adapt to the new environment before feeding.
