The fish tank needs to turn on the lights during the day. Fish tanks are usually not placed in sunny places, because this will lead to algae proliferation and affect water quality. Therefore, the fish tank lamp is needed to supplement the illumination, and the time to turn on the lamp every day is generally 4-10 hours. Light is not only beneficial to the growth of fish, but also can promote some fish to change color and make them more ornamental. In addition, you must turn off the lights at night, so as not to affect its rest.

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.
