Red Arowana can turn on the lights for 6-8 hours a day, because the work and rest time of red Arowana growing in the wild is quite similar to that of human beings, and they all work at sunrise and rest every day. Therefore, when raising artificially, we should try our best to simulate the wild environment. You can turn off the lights after entering the evening and turn them on in the early morning.

Many breeders choose to turn on the lights 24 hours a day in order to make their body colors bright, but this way of turning on the lights is incorrect. Because turning on the lights 24 hours a day will not only affect their normal work and rest, but also make their spirits tense. In addition, turning on the lights for a long time will increase the probability of their eyes and tails falling off. Some lights can also cause their backs to blacken.

When raising red arowana, diving lamp can be selected as the main lamp and double-tube bracket lamp as the auxiliary. The diving lamp can be installed in the area where the red arowana often moves, and the bracket lamp is preferably installed in the middle of the fish tank. In this way, when there is no natural light, you can choose to use diving lights to supplement it. If you want their hair color, you can often spend a lamp. However, the penetrability of the bracket lamp is not strong, so it needs to be used together with the diving lamp.

If the breeder wants to turn on the lights at night, he can install a small LED light on the side, which will not affect the rest of the red arowana, and can see their state at any time at night.
