of arowana is usually between 50-70 centimeters when it grows up, so it is possible to raise arowana in a 120-centimeter-long and 60-centimeter-wide tank. Of course, there are also those with good physique, whose body length can reach 100 centimeters, but this length of arowana is relatively rare. If the breeder has the conditions, he can use a larger fish tank, because the fish tank is large, the arowana has more space to move, which is of great benefit to their growth and development.
? Arowana can be polycultured, but the character of arowana is ferocious and belongs to large fish. Breeders should pay attention to character and body shape when choosing polycultured fish. Fish that are more suitable for polyculture with arowana are parrot fish, map fish, fortune fish, mackerel and so on. First of all, parrot fish and map fish, which are similar in size, bright in color and lively in personality, can be mixed with arowana to enhance their ornamental value.
The second is the lucky fish, which is aggressive in childhood, but more clever in adulthood, and its body length can reach 50 centimeters in adulthood, which is similar to the size of arowana and suitable for polyculture. Finally, the mackerel likes to live at the bottom of the tank, while the arowana lives in the upper part of the tank. They live in different areas and do not have too many intersections and contradictions.
