Is there any sign that arowana jumped out of the fish tank and died?

There are signs that it will appear impatient or try to jump out of the water. There are many reasons why arowana jumped out of the tank, which may be frightened, poor water quality or lack of oxygen. Insufficient activity space will also cause arowana to jump in the tank (arowana is naturally good at jumping). It's normal, yes, I've had this situation before. To put an end to this situation, it is necessary to cover the fish tank or put gauze on the mask.
