Heat a large flat-bottom saute pan over medium heat. Melt the anchovy fillets in a little of their own oil until heated through, then add the white wine. Add the crushed tomatoes, olives, capers, basil, garlic and crushed red pepper if using. Bring the sauce to a boil, then lower to a simmer and cook, covered, for 3 minutes. Add the sea bass on top of the sauce. Cover the pan and poach the fish in the sauce for 6 to 8 minutes.
Add the pasta to the boiling water and cook until firm but not overcooked, 8 to 10 minutes. Drain thoroughly.
Transfer the fish to a warm plate. Toss the pasta into the sauce to heat and coat evenly. Place the pasta on a serving plate and top with the sea bass. Sprinkle on parsley, drizzle with extra-virgin olive oil and add grated or shaved cheese. This is one fish dish that can stand up to added cheese.
