. 1. Reason: Silver arowana is sensitive to temperature difference. If the temperature difference between morning and evening is too large or the temperature difference exceeds 2 degrees when changing water, it will appear upside down.
2. Solution: If you are standing on your head, you can raise the water temperature to 28 degrees first and keep the water temperature constant. Attention should be paid to raising the water temperature slowly, not to 28 degrees at one time, so as not to cause greater impact on the silver arowana.
1. Reason: Poor water quality in the fish tank, low frequency of water change and high feeding density will lead to anoxia of silver arowana. If the anoxia lasts for a long time, handstand will occur.
2. Solution: If it is confirmed that it is due to lack of oxygen, the breeder can open the oxygen pump to explode oxygen, and then open the circulating filtration system to ensure sufficient oxygen in the fish tank. Generally, it can be recovered after 1-2 days.
in time 1. Reason: Silver arowana has higher requirements for water quality. If the water quality in the fish tank is too poor, it will cause them to stand upside down.
2. Solution: The breeder needs to replace the water in the fish tank in time, but not all of it, only one third of it needs to be replaced. When changing water, we should use good water, and the temperature difference between new water and old water should not exceed 2 degrees. Finally, adjust the circulating filtration system to the maximum, and try to keep the water in the fish tank weakly acidic.
