Strong adaptability, can survive even in harsh environment, even without drinking water for 5-6 hours is not fatal.

Pelteobagrus fulvidraco can survive normally when dissolved oxygen is more than 2mg/L, floating head occurs when dissolved oxygen is less than 2mg/L, and suffocation occurs at1mg/L. Pelteobagrus fulvidraco is suitable for alkaline waters, with the optimum range of 7.0-8.5 and the tolerance range of 6.0-9.0. Pelteobagrus fulvidraco has poor tolerance to salinity. After hybridization, it can adapt to 2‰-3‰ sodium chloride, and if it is higher than 3‰, it will die.
