arowana and koi can not be raised together. The arowana is suitable for living in the water temperature environment of 24 to 29 deg C, the koi can survive between 2 and 50 deg C, and the koi can accommodate the arowana in terms of temperature. But arowana can only be cultured in slightly acidic waters, while koi live in alkaline waters, alkaline environment and acidic environment can not coexist, which means that they can not be mixed. Arowana is a carnivorous fish, Koi is an omnivorous fish, eating does not conflict. But the koi is small, and it is hard to guarantee that it will not become the food of the arowana. Therefore, it is recommended to keep arowana and koi separately.
arowana and butterfly carp can be mixed. The optimum temperature for arowana culture was 24 ℃ ~ 29 ℃, and the optimum temperature for butterfly carp was 25 ℃ ~ 30 ℃. There is little difference in temperature between the two species, and the temperature can be controlled above 25 ℃. The water used to breed them can be tap water after sunshine, and then add appropriate amount of salt to adjust PH. Butterfly carp is not picky about food, and can be fed according to the preferences of arowana. The dragon fish is a medium-sized fish, and the butterfly carp is about the same size as it, so you don't have to worry about fighting when you raise it together. Their feeding conditions are basically the same, so they can be raised together.
