Flathead catfish like cover they can get under like submerged trees or undercut banks. They want to have something over their heads either to provide shade or an ambush point they can use to come out of the darkness and strike.
With their large mouths they are capable of engulfing big fish. Flatheads also hunt at night around submerged rock and timber for small fish which tend to use this structure.
If you catch these large predators remember the importance of releasing them for others to enjoy.
