In a medium bowl, combine the flour, cornmeal, paprika, garlic powder, cayenne pepper (if using), salt, and black pepper.
Pat the cleaned fish dry with paper towels.
Dredge each fish in the flour mixture, ensuring they are well coated.
Heat a generous amount of vegetable oil in a large skillet or frying pan over medium-high heat.
Fry the coated fish in batches, without overcrowding the pan, until they are golden brown and crispy, about 3-4 minutes per side.
Use a slotted spoon to remove the fish from the oil and drain them on paper towels.
Enjoy your meal!
