How to deal with arowana after jumping into the tank:

1. Lower the water level. Check whether the fish has completely abnormal swimming postures such as sinking its head, swimming sideways, floating on its back, etc. Consider lowering the water level to allow the fish to adapt to the pressure.

2. Don’t feed. The breeder must resist the urge to feed the fish after jumping out of the tank. In case of internal injury, feeding will only continue to increase the burden.

3. The master cylinder explodes with oxygen. During this damage repair process, oxygen needs to be exploded to provide the fish with a high enough dissolved oxygen level.

4. Slow down the water flow. If the fish's seven fins are damaged and the impact of strong water flow is likely to cause the stem bone to grow crooked during the later recovery, so slow down the impact of the water flow and allow its stem bone to recover as much as possible.

5. Supplement nutrition. Add some vitamins, probiotics, etc. so that the arowana can get enough nutrients to recover.
