Whether Arowana can be saved when it stands up depends on the reasons that cause them to stand up. If they stand up because of lack of oxygen, the breeder only needs to turn on the oxygen pump to ensure that there is enough oxygen in the water where they live, and then they can soon resume swimming horizontally. If the arowana is erected because of a sudden change in the environment, the breeder only needs to ensure that the environment in which they live is stable, and then they can recover in a few days. If it is because of swim bladder, it is difficult to treat. Because congenital swim bladder disease can't be cured, even if it is acquired, it is difficult to treat it.

1. Oxygen: Arowana may stand up because of lack of oxygen, so breeders need to get oxygen immediately to ensure that they have sufficient oxygen. At ordinary times, we should change water frequently, because the new water also contains more oxygen, which can meet most of their daily needs of oxygen.

2. Keep the environment stable: Arowana may also stand up because of sudden changes in the environment, and breeders need to keep the surrounding environment stable. If conditions permit, it is best to install a heating rod to keep the water temperature at 28-30 ℃. Filters should also be installed to slow down the deterioration of water quality and keep the water quality stable.

3. Lower the water level: Arowana erection may also be caused by swim bladder disease. Breeders need to lower the water level first to avoid them keeping upright all the time. If lowering the water level is not effective, the breeder needs to use splints or other heavy objects to tie them to both sides to ensure that they are in a stable state
