1. Reason: Koi and humans have similar schedules. If you see Koi motionless at the bottom of the tank in the evening or early morning, you may be sleeping.
2. Solution: The breeder can judge whether the koi is sleeping according to its work and rest time, or gently pat the fish tank to see if the koi will swim upstream.
. 1. Reason: The water temperature that Koi likes is 20-32 ℃. If the water temperature is too low, there will be a situation of lying in the tank. Because the temperature at the bottom of the jar will be slightly higher than that at the top, if the temperature is too low, the koi will gather and hide at the bottom of the jar.
2. Solution: The breeder needs to raise the water temperature to above 20 ℃ and keep the water temperature stable. If the temperature difference between morning and evening is large, it is necessary to turn on the heating rod for constant temperature.
1. Reason: If the water quality is too poor, it will easily lead to the reduction of dissolved oxygen in the water. If the oxygen is insufficient, the koi will also reduce their activity, and sometimes they will not move at the bottom of the tank.
2. Solution: The breeder needs to change the water in time to ensure the water quality is clean. Oxygen should also be added in time to ensure that the dissolved oxygen in the water is sufficient.
1. Cause: The main cause of Saprolegniasis and white spot disease is that the water quality is too poor or the water temperature is too low. The symptoms of Saprolegniasis and white spot disease are similar in the early stage. In the early stage of the disease, Koi carp will have reduced activity, hide in corners, and reduce food intake.
2. Solution: If the early symptoms are not serious, the breeder needs to immediately raise the water temperature to about 25 ℃, add coarse salt to the fish tank, and then turn on the oxygen pump. If the symptoms are serious, you need to use potassium permanganate solution or oxytetracycline bath, once a day, and you can recover after a week.
