Habitat
This species inhabits freshwater environments such as rivers, lakes, ponds, and swamps, often in warm, tropical regions of Southeast Asia like the Mekong and Chao Phraya basins. It tolerates low-oxygen waters and can survive in temporary pools or even on land, making it adaptable to disturbed or agricultural areas. In introduced regions like Florida, it thrives in canals and drainage ditches.
Diet
The walking catfish is omnivorous, feeding on a variety of items including small fish, insects, crustaceans, plant matter, and detritus. It forages opportunistically, often at night, using its barbels to detect food in murky waters. This feeding behavior makes it a generalist scavenger in both native and invasive habitats.
Behavior
Walking catfish are primarily nocturnal, actively foraging at night and resting during the day in hidden spots. They exhibit territorial behavior, especially during breeding, and can move over land using their pectoral fins to find new water sources during dry periods. This species is known for its aggressive nature, often invading new areas as an invasive pest.
Conservation Status
Listed as Least Concern by IUCN.
