Can a tank 40 cm ? A tank 40 cm wide cannot raise arowana, because the size of arowana is relatively large, generally between 80-120 cm. If a tank 40 cm wide is used to raise arowana, they can only swim back and forth, unable to swim back and forth. Not only will their growth and development be limited, The shape of the bones also changes. In particular, the bones of red arowana and goldfish are relatively hard and cannot be bent under normal circumstances. If they are raised in a narrow tank for a long time, their bones will be deformed. Therefore, a 40-centimeter-wide fish tank is not suitable for raising arowana.
arowana is a large fish, the body length can reach about 100 centimeters, the normal length of the tank to raise arowana should be more than 120 centimeters, the width should be more than 60 centimeters, the height should be more than 70 centimeters. In this way, the growth space of arowana can be sufficient. If the breeder wants to make the body of the arowana healthier, he should prepare a tank 200 centimeters long, 80 centimeters wide and 80 centimeters high for them. Only in this way can the arowana have enough space to move and grow bigger.
The arowana is irascible and has a strong sense of territory, so it is better for the breeder to keep them alone to avoid fighting or fighting. If you want polyculture, you can choose some medium-sized fish.
