The life span of artificially cultured Arowana is about 6-7 years, but the specific time depends on their living environment and feeding methods. If the living environment of silver arowana is comfortable and there is plenty of food and space, then their life span can be longer, generally about 6 years. There are some silver arowana with good physique, and their life span can reach more than 7 years.

If they don't have enough space and live in an unstable environment, their life span will be much shorter. In addition, their ability to resist diseases is not very strong, and they are prone to illness if the environment is unstable. Therefore, the life span will be shortened a lot, and it can only live for 3-4 years.

If breeders want them to live longer, they need to keep the environment stable during the normal breeding process, which can not only prevent them from getting sick, but also make them live more comfortably.

Silver arowana raised in fish tanks generally has a body length of 50-60 cm in adulthood. Because the space in the fish tank is not enough and the water body is relatively small, there will be certain restrictions on their growth and development. If it is a silver arowana cultured in a fish pond or pond, its body length can reach more than 1 meter in adulthood. Because the water body in the pond is larger, they will have more room for movement, so their bodies will develop larger.
