Silver arowana grown in the wild can grow to about 1 meter in adulthood, and its weight is generally about 5 pounds. The artificially bred silver arowana will be smaller, only about 50-70 cm long and weighing about 2-3 kg. Silver arowana growing in different environments has different body lengths in adulthood. In artificial breeding, if you want them to grow bigger, you must first ensure sufficient space. Only when there is sufficient living space can their bodies develop bigger. Secondly, it is necessary to keep adequate food and nutrition, so as to ensure their physique is stronger and avoid getting sick. Finally, we should ensure the stability of the environment, so as to avoid more discomfort.

Although Arowana grows faster, it takes longer to grow up. Under normal feeding, it takes 2-3 years for Arowana to mature. If they live in a comfortable environment and have enough food, they may mature in about 2 years.

In addition, the development speed of male arowana is slower than that of female arowana. It usually takes 3-4 years for male fish to mature, and some slow ones may take 4-5 years.
