1, the reason: the water temperature in the fish tank is too low, the koi will hide at the bottom of the tank, because the water temperature at the bottom of the tank will be a little higher than the upper water temperature. Although Koi can accept lower temperatures, if the water temperature is too low for a long time, it will cause Koi to be inactive and easy to lie at the bottom of the tank all the time.
2. Solution: You can gradually raise the water temperature to about 25 degrees when changing the water, or you can use a heating rod to maintain the water temperature between 20-25 degrees.
1. Reason: The water quality in the fish tank is poor and the filtration system is not perfect enough, which will lead to low dissolved oxygen in the fish tank. The high density of feeding will also lead to the reduction of oxygen content in water. If there is a lack of oxygen, the koi will easily lie in the tank.
2. Solution: Clean up the feces and food residues in the fish tank in time, change the water frequently, and sterilize if possible. An oxygen pump should be installed in the tank to ensure sufficient oxygen in the tank.
1, the reason: Koi for a new environment, no sense of security, will also lead to lying tank.
2. Solution: The breeder can interact with the koi more, such as observing beside the fish tank or feeding in person, which can make the koi get familiar with the environment quickly and reduce discomfort.
1. Cause: Koi is infected by bacteria or parasites, which will lead to the decline of physiological state, and it is easy to appear that they do not like to move and lie in the tank.
2. Solution: First, raise the water temperature in the fish tank to 28 degrees, then use yellow powder to give the sick fish a medicinal bath, or add coarse salt according to the proportion of five thousandths, about 2-3 days can be cured. During the treatment, water should be changed frequently to keep the water quality good.
