for goldfish to bask in the sun a day? Although it is good for goldfish to bask in the sun properly, it is necessary to arrange the time of basking in the sun reasonably and avoid exposure at noon when the sun is strong. Too much time in the sun will make the algae in the fish tank grow too vigorously, which will cause the water quality of the fish tank to deteriorate and adversely affect the growth of goldfish. It is easy to cause sunburn when the goldfish is exposed to strong sunlight or exposed to direct sunlight for a long time.
Generally speaking, in the spring and summer when the sun is stronger, goldfish only need to be exposed to the sun for 1-2 hours a day. In autumn and winter, when the sun is relatively weak, the time can be extended to 3-4 hours. When encountering continuous rainy weather and insufficient sunshine, light sticks and other equipment can be used instead of sunshine to continue to "sun" the goldfish.
