What is the omen of the death of Arowana depends on the cause of their death. If they are infected with diseases and germs, it means that the water in the fish tank contains a large number of bacteria. The breeder needs to replace all the water and clean the fish tank with potassium permanganate solution. If they die because the temperature is too low or the temperature difference is too large, it means that the water temperature in the fish tank is unstable, and the breeder needs to install a heating rod in the fish tank.

1. Constant water temperature: If silver arowana is not easy to die, it is necessary to ensure their living environment is comfortable. They are sensitive to changes in water temperature, and breeders need to ensure that their living temperature is around 28 ℃. The temperature difference should not exceed 0.5 ℃ when changing water.

2. Clean water quality: Silver arowana also has high requirements on water quality. If breeders want them to survive well, they must ensure that the water quality they live in is clean and refreshing. If conditions permit, the PH value can be kept between 6.5 and 7.5. Usually, we should change water in time, preferably once every 2-3 days. However, the amount of water change should not be too large, and it should be controlled at one third of the total amount of water.

3. Reasonable feeding: Silver Arowana prefers animal feed, and breeders should pay attention to the feeding amount when feeding. Moreover, we should pay attention to feeding less foods with high fat content to avoid fat accumulation. If conditions permit, they can be installed with a wave-making pump, so that they can move regularly.
