Ding Gui fish is a kind of freshwater and benthic fish with wide temperature, which is common in calm waters with rich plants based on clay and mud, but rare in stony and clear waters, and it can't be found in fast-flowing streams at all.

Resistant to low dissolved oxygen, can tolerate water with low oxygen content and even waters where carp can't live. It can survive in water at 0℃ ~ 40℃, and the optimum growth temperature is 20℃ ~ 28℃. The pH value is 7 ~10. Living in slow-flowing fresh water, especially in the lower reaches of lakes and rivers.

Living in deep water in winter, it has strong cold resistance and belongs to wide temperature. Usually spawn in summer and grow rapidly. Omnivorous, mainly benthic invertebrates, algae and humus. Natural resources are decreasing. As an excellent breeding object, it has been popularized in many places in China.

Extended data:
