1. Reason: Silver Arowana lying on the bottom of the tank may be caused by too low water temperature or too large temperature difference. They are sensitive to environmental changes. If the water temperature changes, stress reaction will appear. Also, if the water temperature is too low, they will lie prone on the bottom of the cylinder, because the water temperature at the bottom of the cylinder will be higher than that at the upper floor.

2. Solution: Breeders need to raise the water temperature to 28 ℃. When heating up, they should not raise it too much at one time, otherwise they will also feel uncomfortable. They need to be lifted slowly, and it is best to wait for them to adapt to the water temperature before lifting.

1. Reason: Silver arowana lying on the bottom of the tank may also be frightened. Although they look domineering on the outside, they are actually less daring. If there is a loud noise around them or someone slaps the fish tank vigorously, they will be frightened.

2. Solution: The breeder should first keep the surrounding environment quiet and minimize the disturbance to the silver arowana. If they don't have a low appetite, don't feed food all the time. After they recover from the frightened mood, the situation of lying on the cylinder will be relieved.

1. Reason: Silver Arowana may lie prone to the tank because the water quality changes too much, and they are also sensitive to the change of water quality. If the temperature difference is too large or the amount of water change is too large, they will also lie prone to the tank.

2. Solution: The breeder needs to restore the previous water quality as much as possible and turn on the filter to ensure the water quality is clean. After waiting for a period of time, they can recover.
