It has strong adaptability and can live in 3% salt water and acid-alkaline water with a certain concentration. When the dissolved oxygen in the water is close to zero or in long-term hypoxic odorous water, some individuals can still survive and swallow larvae. The suitable water temperature range is 4.5~40℃, and the optimum water temperature is 18~30℃. In summer, they are afraid of heat, and they descend and disperse after sunrise; in winter, they like the sun and when the weather is sunny and warm, they often swim to shallow water and spend the winter in a ditch with a water depth of 1 meter.
