Life habits:
Pelteobagrus fulvidraco mostly inhabits shallow waters around the lake with slow-flowing water plants and rivers entering the lake, and lives in benthos, especially in still water or slow-flowing shallows where there is much humus and mud. During the day, they lurk under the water or in crevices of rocks, move and forage at night, and gather in deep water in winter. Strong adaptability, even in harsh environment, it can survive, and even 5-6 hours without water is not fatal. Pelteobagrus fulvidraco is resistant to hypoxia, and it can survive normally when dissolved oxygen is above 2mg/L, and when dissolved oxygen is below 2mg/L, it will appear floating head phenomenon, and 1mg/L will suffocate and die.
The survival water temperature is 1-38℃, and the uncomfortable reaction occurs when the temperature is 0℃.
The feeding habit is omnivorous, mainly animal feed under natural conditions, zooplankton in the fry stage, insects and their larvae, small fish and shrimp, snails and mussels in the adult fish, and plant debris are also swallowed.
