Silver arowana does not have too high requirements on the color of the lamp. Breeders can choose to use three primary color white tube lamps, which have better illumination layering and stronger color development than other lamps, and are very suitable for being placed in aquarium tanks. Breeders can also choose ordinary pale yellow lights, but this kind of lights only have the function of lighting.

If the breeder has the conditions, it is best to let the silver arowana receive natural light, because the wild silver arowana moves in the upper layer of the water and can receive more sunlight during the day. When raising artificially, try to simulate the wild environment, which can make them grow better.

Silver arowana can turn on the lights during the day. As mentioned above, they can receive more natural light during the day when they are in the wild, and they will also enter darkness at night. Therefore, their work and rest are similar to those of us human beings, and they all work at sunrise and rest at sunrise. When raising artificially, they can turn on the lights during the day, and turn on the lights for 8 hours every day, which can meet their demand for light.

Many breeders often turn on the lights 24 hours a day for ornamental effect, which has great influence on the health of Arowana. Moreover, if the lights are turned on for a long time, they will always remain tight, which will have a great impact on their mental state.
