Living habits: Catfish mainly live in rivers, lakes, reservoirs and potholes, mostly in coastal areas, hiding in grass, rocks or deep water during the day and foraging frequently at night. Living in deep water or mud for the winter after autumn, the degree of food intake is also weakened. Carnivorous fish mainly prey on small fish, such as rice sticks, crucian carp, goby fish, ear fish, carp, loach and so on. And eat shrimp and aquatic insects. Mainly swallowing, the role of teeth is mainly to prevent food from escaping.
It's Nocturnal Animals, hiding quietly in the pit at the bottom of the river or under the roots during the day. Large species with a big appetite, such as the Danube catfish, attack small waterfowl or mice and fierce fish at the bottom. Afraid of light, I like to live in crevices, deep pits, earth caves or caves at the bottom of tree roots, and slow flowing water near rivers.
In the still water of reservoirs, ponds, lakes and ponds, most of them lie under dark water or under pieces of water hyacinths, water peanuts and water hyacinths.
In spring, we start to move and eat. Don't eat after winter, stay in deep water or caves for the winter, and generally don't swim if there is nothing to invade.
