The body length of silver arowana can reach 90-120 cm, and the specific growth depends on their environment. Silver arowana is a large fish. If it grows in the wild or in a wide space, it will be larger in adulthood. It can grow to about 120-130 cm. If it is a silver arowana raised in a fish tank, its size will be smaller, about 80-90 cm. Because they don't have enough space to live in, they will have less activity and will not grow very big. Even if they are properly raised and have plenty of space, they can only grow to 90-100 cm, and it is difficult to grow to about 120 cm.
If breeders want to make silver arowana bigger, they should feed them more nutritious food. It is also necessary to ensure that their living environment is comfortable, so that their body size can develop bigger.
2. How old can Arowana reproduceThe artificially raised Arowana generally mature in about 5 years, and can reproduce when their body length reaches 50-60 cm. But with different feeding methods, their adult time is also different. Normal silver arowana can grow to 50-60 cm in 5 years as long as it is properly fed. If the breeding environment is poor and the space is not enough, they may mature in less than 50-60 cm.
