There are many varieties of Arowana, and different varieties have different background colors. It is best for breeders to choose the color of lights according to their background color, so as to make them more ornamental. If it is golden-bottomed Arowana, the breeder only needs to use a yellow LED light. Because the golden-bottomed Arowana is matched with yellow lights, the scales can have reflective effects and look metallic. If it is a blue-bottomed Arowana, use blue and warm white LED lights, because the blue-bottomed Arowana can see obvious blue when swimming, and matching blue with warm white can also make their scales more glossy.
When breeders install aquarium lamps for Arowana, it is best to choose the combination of overhead lamps and underwater lamps, so as to avoid eye drop and uneven light.
2. How long does the Arowana turn on the lights every dayIf the Arowana cannot receive natural light, the breeder needs to turn on the lights for 8-10 hours every day. Because they are pelagic fish, they can receive plenty of natural light when they grow in the wild. But in the wild, as the sun sets, their living environment will fall into darkness, so breeders can simulate the native environment and turn on the lights for 8-10 hours a day.
If Arowana can receive natural light, breeders do not need to deliberately supplement lighting. Because the effect of natural light is better than that of light, and natural light has the function of sterilization and disinfection.
