There are three signs that the arowana suddenly jumps out of the tank. One is that it may be frightened. It is best not to disturb it at ordinary times, and pay attention to changing the water and turning on the lights. Second, due to sudden changes in water temperature, it is necessary to strictly control the water temperature difference and the temperature in the fish tank. Third, because the density is too high, the arowana shows signs of hypoxia and needs to be supplemented with oxygen or raised alone. 1. Frightened
Arowana may be frightened when it suddenly jumps out of the tank. Arowana is timid and very nervous. When someone approaches the tank, Arowana will jump. The inside of the fish tank is scurrying around. Big water changes, turning on lights suddenly, raising new fish, etc. may cause the arowana to be frightened. 2. Sudden changes in water temperature
The nerves of arowana are relatively sensitive. When the water temperature changes, especially when the water temperature changes suddenly, it will cause the arowana to jump out of the tank. In this regard, raising arowana requires strict temperature control, including the water temperature difference when changing water, to prevent the arowana from jumping into the tank. 3. The density is too high
Arowana is usually kept alone. If it is mixed with other fish, if the arowana jumps out of the tank, it is usually because of the breeding. The space is too small, and the breeding density is too high at this time. The owner needs to strengthen the oxygen supply, or raise arowana alone.
