1, parrot fish and map fish are generally the first choice for polyculture with arowana. If it is used as a match fish, the grade is a bit low, but these two kinds of fish are relatively docile and their colors can be in sharp contrast with arowana. For example, a small arowana about 50 cm can be matched with seven or eight parrot fish 10 cm, or two or three map fish can be used.

2. Lucky fish is also a regular companion fish of arowana. He was aggressive when he was a child and became more clever when he grew up. Because his individual can grow to more than 50 centimeters in two years, we can choose an individual whose body length is smaller than that of arowana and keep only one.

Tiger fish in Thailand is often used as companion fish in golden dragon tanks, and the largest individual can reach 50 cm. Tiger fish is not very active, and it brings out the best in arowana. Many fish friends also want its dragon and tiger meaning. Generally speaking, it is enough to raise another tiger fish in the dragon fish tank.
