The loach likes to live in the bottom of the static water, often in lakes, ponds, ditches and paddy fields at the bottom of the silt surface layer rich in plant debris, strong adaptability to the environment. The living water temperature is 10～30℃, and the optimal water temperature is 25～27℃, so it should be a warm water fish. When the water temperature rises to 30℃, the loach dives into the mud in summer. In winter, when the water temperature drops to below 5℃, the loach dives into the mud at a depth of 20-30cm to overwinter.

The loach can not only use the gills and skin respiration, but also has a special intestinal respiratory function; when the weather is hot and stuffy or the bottom of the pool silt, humus and other substances rot, causing severe oxygen deficiency, the loach can also leap out of the water, or rise vertically to the surface, with the mouth to swallow the air directly, and by the intestinal wall of the assisted respiration, when it turns its head and dives down slowly, the exhaust gas is discharged by the anus.

Whenever this happens, the loach in the entire body of water rises to the surface to inhale, one after another, so Western Europeans have it "climate fish". Winter cold, the water body dries up, the loach will be drilled into the mud, relying on a small amount of water to keep the skin from drying out, and rely on intestinal respiration to maintain life. When the water rises in the following year, it will go out again.
