It is better to use blue and white lights in fish tanks. Tricolor lamp is a fluorescent lamp, which belongs to the traditional aquarium lamp. At present, it is widely used and the price is not high. Blue and white lamps belong to LED lamps, which are gradually emerging as new aquarium lamps. Compared with traditional fluorescent lamps, their prices are higher, but because they are cold light sources, they are safer and have a long service life. However, from the perspective of color development, tricolor lamps are better.

1. Promoting growth: The main role of fish tank lamp is to promote the growth of fish. Although fish live in water, they still need a certain amount of light. If they are always in a dark environment, their growth will be limited, so they need proper light, but the light time should not be too long.

2, which is beneficial to hair color: Some ornamental fish will change color during growth, and there are many ways to induce their hair color, and illumination is one of them, so fish tank lights are also needed. It should be noted that different fish have different needs for light, and some pigmented feed should be used besides light.

3. Easy to watch: With the fish tank lamp, it becomes convenient to watch. The fish in the tank and the landscaping can be seen at a glance, so as to better observe the swimming posture of the fish and find out the abnormal state of the fish as early as possible, which is very helpful for treatment.
