Red arowana can live for about 20-50 years, and how long they can live depends on the breeding environment and mode. Under normal circumstances, wild red arowana can live to 40-50 years, because the living environment in the wild is comfortable and there is plenty of space, so their life span is longer. The average life span of artificially raised Arowana is only about 20 years due to the influence of feeding methods and containers. Because artificial breeding is mostly put in fish tanks, not only the space is small, but also the living water temperature and water quality are unstable, so their life span will be relatively short.

Raise arowana artificially in order to make them live longer. First of all, we must ensure that their living environment is comfortable, secondly, we must ensure that they have enough food, and finally, we must pay attention to prevent diseases.

The body length of the red arowana can reach 50-100 cm in adulthood, and the red arowana grown in different environments has different body shapes in adulthood. If it is a red arowana growing in the wild, its body length is about 80 cm in adulthood, and some can grow to about 100 cm. The length of artificially raised red arowana is generally about 60 cm, and some have enough space to grow to about 80 cm, but few can grow to 100 cm. If there is not enough space to keep them, they will not grow very big.
