Silver Arowana can adapt to neutral water quality and water temperature above 22℃, and the optimal temperature is 24-28℃. The water quality should be clean and tap water should be treated. The amount of water exchange should be small, and the pH and temperature of the added water should be appropriate. A large 1.5-meter-long box is used for raising aquariums, and there is no need to lay sand and plant grass, because silver arowana often goes to the upper layer, and the surface water swims, and the box mouth is covered with a net to prevent jumping. To keep the water clean, the filter should always be open. The water quality, environment, bait and other conditions are good, and it can grow up to 50-60 cm in one year. It can be fed with small fish, shrimp and goldfish, as well as meat and insects.

The water temperature of silver dragon fish is lower than 25 degrees, or even lower than 22 degrees If it is too high, it will cause the silver arowana to swim slowly, lose its appetite, and have a phenomenon of refusal to eat, and its resistance will decrease.

The higher the water temperature, the greater the oxygen consumption of fish. The water temperature of silver arowana is higher than 28 degrees, and within the range of 28-32 degrees, it is easy to cause different degrees of hypoxia in silver arowana. If it exceeds 32 degrees, it will seriously affect the life safety of silver arowana.
