The life span of wild red Arowana is generally between 30 and 40 years, which is relatively long compared with other Arowana. The life span of artificially raised red Arowana is generally between 15 and 20 years, but how long it can live depends on the way of raising and their physique. They can live up to 20 years if they are raised properly and have plenty of food and space. If they live in a poor environment and have insufficient food and nutrition, their life span will be shorter. Some people who often get sick will live a shorter life.

The body length of the wild red Arowana can reach about 80-90 cm in adulthood, and how long the artificially raised red Arowana can grow depends on the container and method of feeding. If the container is larger and the food and nutrition are sufficient, their body size can also develop larger. If the containers are small, they will not develop very big.

If you want the red Arowana to grow bigger, you should prepare a larger container for them, so that they have enough room to move. It is also necessary to ensure that they have enough food, so that they have enough nutrition to develop their body shape. Finally, regular sterilization should be carried out to avoid diseases.
