The Pelteobagrus fulvidraco, also known as Pelteobagrus fulvidraco, is a species of catfish in the family Pelteobagrus (catfish), which is also known as Pelteobagrus fulvidraco. It is also known as yellow rattail, gajako, yellowfin fish, and yellow spinebone, and is widely distributed in various Pacific water systems in eastern China. It lives in still water or slow-flowing shallows, and emerges day and night. Body length 123-143mm, omnivorous, staple benthic invertebrates, food for small fish, aquatic insects and other small aquatic animals. spawning in April-May, the parent fish have the habit of digging pits to build nests and protect the offspring. During the reproductive period, males have the habit of building nests. Pelteobagrus fulvidraco is mostly active in still water or slow-flowing rivers, and lives in benthic habitats. During the daytime, it inhabits the bottom layer of the lake, and at night, it swims to the upper layer of the water to forage for food. It has a strong ability to adapt to the environment, so it can also live under adverse environmental conditions. Juvenile fish mostly forage along the shoreline of rivers and lakes.　The fish is a warm water fish. The survival temperature is 0~38℃. The optimal growth temperature is 25~28℃, pH range is 6.0~9.0, and the optimal pH is 7.0~8.4. The ability to tolerate low oxygen is average. Dissolved oxygen in the water above 3mg / L when the growth is normal, below 2mg / L when the floating head, below 1mg / L will suffocate and die.
