Heat oven to 250° F.
Dip each fillet in flour, shaking off excess. Melt 3 tablespoons butter in a 12-inch nonstick skillet over medium-high heat until bubbly. Add 3 fillets, skin side down, and cook until golden brown and skin is crisp, 2 to 3 minutes. Turn and cook 2 to 3 minutes more, until golden brown. Transfer fillets to a platter; keep warm in oven. Wipe out skillet. Melt 3 tablespoons butter in skillet and repeat cooking remaining fillets.
Meanwhile, melt remaining 6 tablespoons butter in a small saucepan over medium heat. Stir in lemon juice. Spoon almonds then butter sauce over each fillet. Serve with lemon wedges.
