Rinse the fillets and pat them dry with paper towels. Mix the cornmeal, flour, salt, creole seasoning, paprika, and pepper together in a shallow dish. Pour the milk into a second shallow dish. Dip the fillets into the milk and then into the cornmeal mixture, coating them well and shaking of any excess.
Heat 1/2 the butter in a large skillet over high heat, and fry 2 of the fillets for about 3 minutes on each side, or until the fish flakes easily when tested with a fork.
Transfer the fillets to a serving platter and keep warm. Repeat with remaining butter and fillets. Serve immediately, garnished with lemon wedges.
