In an 11×7-inch baking dish combine orange, lemon and lime juices, cilantro, oil, garlic and fajita seasoning. Add fillets, turning to coat. Let stand 10 minutes.
Bake 10 to 12 minutes or until fish flakes easily with a fork. Transfer fillets to a serving platter and cover loosely with foil to keep warm.
Pour pan juices into a small saucepan over high heat. Bring to a boil and cook until reduced to 3/4 cup.
Spoon sauce over fillets, and serve with citrus wedges if desired.
