1. Keep the water temperature constant 1. Reason: Silver Arowana with its head up may be due to stress reaction caused by too large temperature difference, which is usually caused by using cold water when changing water.
2. Solution: Breeders need to raise the water temperature to above 28 ℃ first, and then they can gradually recover after adapting to the new temperature. Usually, it only takes 1 day, and they can be relieved.
2. Supplementing oxygen1. Reason: Silver Arowana may also be due to lack of oxygen. If they suffer from lack of oxygen, they will try to extend their heads to the water to breathe fresh air.
2. Solution: Breeders need to turn on oxygen immediately to ensure sufficient dissolved oxygen in their water. Then raise the water temperature to about 28 ℃, and finally add some crude salt. Wait for a while, and they will recover soon.
3. Lower the water level and keep balance1. Reason: Silver Arowana may also suffer from swim bladder loss with its head upright, which is congenital and acquired. Acquired swim bladder disease is mostly caused by low water temperature or food scratching internal organs.
2. Solution: Congenital swim bladder loss of Arowana is generally difficult to cure, and acquired swim bladder loss is more likely to be cured. When breeders find that they suffer from swim bladder disease, they should immediately lower the water level and stop them from moving upright. If the swim bladder loss is serious, you can fix them with splints or foam, then keep the water temperature constant, and feed them some anti-inflammatory drugs such as amoxicillin and oxytetracycline.
