Guppies are a kind of tropical fish. Judging from their native environment, they can bask in the sun. After proper sun irradiation, the fish can grow better and the appearance of the fish is more beautiful and bright. In addition, ultraviolet rays in sunlight can eliminate harmful substances in water and effectively prevent fish from being infected with various skin diseases. Therefore, the benefits of this fish basking in the sun are many. However, there are also problems to be paid attention to when it is exposed to the sun. When you are in the sun, you can't expose yourself to the sun, especially at noon in summer, because the ultraviolet rays are too strong at this time, and the temperature of the water is very high, so it's easy to sunburn or kill the fish.
Under normal circumstances, this kind of fish drying time can be adjusted according to the temperature. If the temperature of the day is relatively high, it can provide 1-2 hours of light every day. If the temperature of the day is relatively low, it can provide a longer period of light, 3-4 hours is better. The exposure time per day is preferably not more than 5 hours. If there are no plants in the tank, you need to leave some shade for the guppies, and don't leave the tank completely in the sun. The best time for guppies to receive light is in the morning and afternoon, not at noon. Because the light will be very strong at noon. Especially at noon in summer, the light is very strong, so we must avoid direct sunshine.
