The fish tank can bask in the sun. Proper light is helpful to fish, which can promote their eating and hair color. However, it should be noted that long-term illumination will increase the risk of algae explosion. Once algae multiply in water, it will consume too much oxygen and pose a threat to the health of fish. At the same time, exposure of fish tanks in places with strong light will also reduce their service life.

1. Increase the temperature difference: The first problem that fish tanks have to face in basking in the sun is that the temperature rises. Because it will cool down at night, it will increase the temperature difference between day and night. Excessive temperature difference will affect the health of fish, and even lead to stress reaction, resulting in their death. Therefore, we must pay attention to temperature control and cannot bask in the sun when the light is strongest.

2. Algae reproduction: There are two important factors in the growth and reproduction of algae, one is whether the water body is fat or not, and the other is whether the light is enough. Adequate light and eutrophic water will lead to algae outbreak, which will lead to a large amount of oxygen in the fish tank, resulting in fish unable to breathe.

3. Life of fish tank: Fish tank is generally made of glass, and glass should be glued together. The life of this glue will be shortened in high temperature environment, which will lead to water leakage of fish tank and seriously reduce its service life.
