24 hours a day? The arowana does not need to turn on the light 24 hours a day, because the arowana in the natural environment live in the upper waters, so they receive more sunshine, but the time they receive sunshine is only in the daytime, so the family breeding is to simulate the natural environment. Turn on the light for about 8 hours a day. In addition, the work and rest time of arowana is similar to that of human beings. At night, they will fall asleep. If the light is turned on all the time at night, it will disrupt their work and rest time, which will not only affect their normal development, but also make their mental state worse. Therefore, breeders can turn on the lights for 8 hours during the day and turn them off in the evening.
for arowana? There are many kinds of arowana, such as golden arowana, silver arowana, red arowana, etc. These fish have different colors, so they have different requirements for lighting. Like goldfish and silver arowana, blue and white led lights can be used, and the color temperature can be above 3000 K. If it is a high-backed goldfish, you can use a plant lamp and a blue-white led lamp, the background color can be white, and then change to black after the color of the goldfish. Like red arowana, it needs a variety of light collocation to promote hair color, the more common is the diving lamp with double-tube bracket lamp, diving lamp is best installed in the place where red arowana often swims, so as to be effective.
