There are still many mixed fish with red arowana, such as flying phoenix and tiger fish, which can be mixed with red arowana. Flying phoenix and tiger fish are ornamental fish like red arowana, and their living habits are similar, so they are also very suitable for raising with red arowana. Nowadays, many families like to raise red arowana, but only one kind of fish will feel monotonous in the fish tank, so they usually choose a variety of ornamental fish for polyculture.

In selection, fish with similar habits should be selected for polyculture, otherwise it is easy to cause fish death due to unsuitable conditions. In addition, pay attention to the size of fish, and choose about the same size, otherwise it is easy to lead to food grabbing among fish.

Although mixed fish culture is better, it will give many people a headache when arranging the fish tank. In polyculture, you can put more aquatic plants in the fish tank to ensure sufficient dissolved oxygen in the fish tank. If you want to mix ornamental fish, the filtration system must be indispensable, otherwise it will easily lead to water pollution and various fish diseases. In addition, fish also need lighting, so lamps are still necessary. Water temperature has a great influence on fish, so it is necessary to equip heating rods.
