The reason to turn on the light for the fish tank is to meet the light needs of the creatures in the fish tank. Light can not only accelerate the growth and development of fish, but also provide the water plants in the tank with the light necessary for photosynthesis and help them grow better. In addition, some fish and shrimp can also be colored by the stimulation of light. In addition to meeting the needs of the creatures in the tank, turning on the light can also help to increase the ornamental nature of the fish tank and improve its ornamental value. 1、 Do you need to turn on the light in the fish tank? When raising fish, you can place a light in the fish tank. The light can play a lot of roles. If possible, you'd better prepare one. Of course, lighting is not necessary, but can also be replaced by natural light. However, in case of cloudy and rainy weather, that is, when the natural light is insufficient, it is recommended to supplement it with artificial light, that is, light. However, when turning on the light, it should be noted that it is not necessary to turn on the light at all times. The time of turning on the light every day should not exceed 10 hours, otherwise it is also harmful. 2、 The reason why the fish tank should turn on the light has been described above. When raising fish, you can prepare a light in advance and turn it on for a period of time every day, because there are many lighting effects. Specifically, there are several reasons for turning on the light:
1. Biological needs: first of all, the normal growth of organisms in the fish tank needs light. For example, in the process of raising fish, the growth and development of fish need light. Light can make their development state better and their color more beautiful. Moreover, some plants in the fish tank also need light. They need light for their growth, reproduction and normal photosynthesis. Of course, the time of turning on the light should not be too long, otherwise the normal water environment in the fish tank will be damaged.
2. Viewing needs: we generally cultivate fish for viewing, so we can improve the viewing through some measures, such as placing a lamp in the fish tank and selecting the lamp with the most appropriate color, so that the viewing will be stronger on the whole. （YuGangXuYaoKaiDengMa，WeiShenMeYaoKaiDeng）
