Under normal feeding conditions, Arowana can grow to about 60-120 cm in three years. Their growth rate is relatively fast compared with other fish. As long as the breeder can ensure their living space and sufficient food, they can grow to 60-120 cm in three years. Under normal circumstances, the silver arowana can grow to 50-80 cm in the first year of its birth.

By the second and third years, their growth rate will gradually slow down. However, how big the silver arowana can grow in three years depends on their living space. If they don't have enough living space, they can only grow to about 60 cm in three years. If they have enough living space and nutrition, they can grow 80-120 cm in 3 years.

1. Adequate space: If breeders want Arowana to grow faster, they must first prepare a sufficient living space. Only when there is enough room for movement can their bodies develop bigger. Silver arowana is 60-120 cm long in adulthood, so breeders need to prepare at least a 120 cm long fish tank for them, so that they can have enough room for movement.

2. Adequate food: Silver arowana needs more nutrients for its growth and development. In the critical stage of their growth, breeders need to ensure that their food is adequate. Usually, they should be fed more high-nutrition food, so that they can grow faster.
