It takes 5-16 years for Arowana to grow up under normal feeding, but their specific adult time is affected by feeding methods and gender. For Arowana growing in the same environment, it takes 6-12 years for females to mature, while it takes 5-15 years for males to mature. Besides the influence of sex, the way of feeding also has a great influence on their adult time. If they live in a comfortable environment, their adult time will be shorter. If they live in a poor environment, it will take them longer to reach adulthood.

How big Arowana can grow is affected by feeding containers and methods. If it is a wild Arowana, its body length can reach 100 cm in adulthood. If it is raised in a fish tank, the body size will be much smaller, and the body length in adulthood will be between 50-60 cm. However, if they are raised in ponds or larger containers, their body length can reach about 70-80 cm.

If you want to make Arowana bigger, you must first ensure that they have enough living space, because only when there is enough space for activities can their body develop better. Secondly, it is necessary to ensure their adequate nutrition. At ordinary times, they should be fed more high-nutrition foods so that they can have enough nutrition to develop their body shape. Finally, it is necessary to ensure that their living environment is comfortable. They are sensitive to changes in the environment. If the environment is poor, their body shape will not develop very well.
