1. Hypoxia: It is possible that the silver arowana stands up because there is too little oxygen in the water, and their demand for oxygen is relatively large. If the dissolved oxygen in the water is too small, they will suffer from hypoxia. When the lack of oxygen is serious, the silver arowana will stand up.

2. Poor water quality: Silver arowana may stand up because the water quality is too poor. They like clean water quality. If the water quality in the fish tank is too poor, they will also have their heads up.

3, swim bladder: Silver Arowana may also stand up because of swim bladder, which is congenital and acquired, and acquired mainly because the temperature is too low or food scratches the internal organs.

Whether the silver arowana is saved when it stands up depends on their situation. If it is due to lack of oxygen, it is saved. Breeders only need to raise the water temperature to 28 ℃, then add 1% crude salt to the water, and finally explode oxygen. At this time, wait for a while, and they can recover.

If it stands up because of poor water quality, it can also be saved. Breeders can replace one-third of the water first, and then strengthen the filtration in the fish tank, and they can recover in about one day.

If it is due to swim bladder disease, recovery is difficult. Because it is difficult to treat swim bladder, especially congenital swim bladder, it is difficult to recover. If it is acquired swim bladder, you can strengthen the arowana first, then feed some anti-inflammatory drugs, and finally raise the water temperature to 28 ℃.
