Arowana cannot be raised in a 40-cm-wide fish tank, because Arowana is too large, and the length of Arowana grown in the wild is about 100 cm after adulthood. Even if the size of artificial breeding will be smaller, it will generally grow to about 60 cm. In addition, their bones are harder than those of silver arowana, and they can't bend their bodies well when turning, so it may be difficult to turn when cultured in a 40 cm fish tank.
If it is a juvenile Arowana, it can be farmed for a short time, but it is recommended that the breeder prepare a large fish tank for them directly. Because they are sensitive to environmental changes, changing the environment frequently may affect their growth and development. To raise Arowana artificially, it is best to choose a suitable fish tank according to their size.
2. How big a tank can raise ArowanaAs mentioned above, Arowana belongs to large fish, and its body length can reach 60-100 cm in adulthood. Breeders should at least prepare a fish tank 120 cm long, 60 cm high and 70 cm wide. Only in this way can they move normally. If breeders want to ensure that they have enough living space, they need to prepare a fish tank with a length of 200 cm, a width of 80 cm and a height of 80 cm, so that their body shape can develop better.
