can silver arowana grow in a year? Silver arowana can grow 50-80 centimeters in the first year after birth, and only 20-30 centimeters in the second year after birth. If the usual feeding environment is better and the food is more abundant, it can grow about 10 centimeters a month. The growth rate of juvenile arowana is relatively fast, and it only takes 15 days to grow from 10 centimeters to 20 centimeters. But it takes about 60 days from 20 centimeters to 30 centimeters, and the growth rate of silver arowana will gradually stabilize after 30 centimeters. Silver arowana can grow up to 90-110 centimeters, or up to 120 centimeters if there is enough space.
1, space: silver arowana size is relatively large, in order to make them grow rapidly, it is necessary to prepare a large fish tank for them. An adult silver arowana can reach 90-110 centimeters in size, and breeders need to prepare at least one tank of more than 150 centimeters.
2. Feeding: If you want the silver arowana to grow fast, you need to feed them more high-protein food. Silver arowana likes to eat some small fish, shrimp, loach, frog, grasshopper, etc. Although silver arowana likes to eat these foods, but the breeder can not feed them for a long time, because the nutritional value of these foods is relatively high, long-term feeding may lead to silver arowana eye loss.
