It is raining. How boring is fish?

In this case, the small fish will have symptoms such as floating head and anorexia.

When it rains, the air pressure will decrease, which will affect the solubility of oxygen in the water, so that the oxygen content in the water will decrease, and fish will have symptoms such as floating head, anorexia and swimming weakness when they are in anoxic water for a long time.

When it rains, the weather will become gloomy, affecting the light in the water, making the plants in the water unable to carry out photosynthesis, thus reducing the source of oxygen in the water. At the same time, gloomy weather will also make fish feel uneasy, thus aggravating boredom.
