why Koi is always at the bottom of the fish tank? 1. The water temperature is too low: The suitable water temperature for Koi is 18-28 degrees, but their favorite water temperature is about 25 degrees. If the water temperature is low, it will cause them to lie on the bottom of the tank, because the temperature at the bottom of the tank is relatively high. If the water temperature is too low all the time, it can also cause the koi to catch a cold or be infected with bacteria.
2. Poor water quality: Poor water quality will lead to poor mental state of Koi, which does not like to swim and often stays in the corner.
3. Frightened: Koi are timid and will be frightened when they just enter the tank or are chased by other fish. They will also be frightened when the external sound is loud or someone beats the tank.
4. Disease: Bacterial infection or gill rot can also make koi weak and unable to swim like healthy fish, so they stay at the bottom of the tank.
if the koi is always at the bottom of the fish tank? 1. Raise the water temperature: If the water temperature is too low, the breeder should raise the water temperature to about 25 degrees, but not quickly, so as to avoid the discomfort of the koi caused by the large temperature difference.
2. Maintain the water quality: If the water quality deteriorates, the breeder can change the water first. When changing the water, put some bactericidal powder in the fish tank, such as yellow powder, and then maintain good water quality.
3. Rest: If you are frightened by the fish chasing in the fish tank, you can rest the frightened koi alone. If you are frightened by external factors, you can change the fish tank to a quiet place to rest.
4. Medicated bath: If it is due to bacteria or gill rot, you can first raise the water temperature to 28 degrees, and then add mercurous nitrate or yellow powder for medicated bath. Finally, change the water every day, and you can recover after a week or so.
