In a large bowl, combine the sea bass, lime juice, lemon juice, orange juice, and onion. Mix all of these ingredients together and let marinate for 4 hours, covered, in the refrigerator.
Preheat a grill.
Once the fish has marinated, add the cilantro, roasted peppers, corn, and season with salt and pepper.
To make the masa cakes, combine the masa flour, eggs, and add a tablespoon of water at a time and form a paste. Make sure the paste is firm and not too watery. Form small pancake shapes and grill on each side for approximately 2 minutes.
To serve, place the masa cakes on the plate and top with the sea bass ceviche. Drizzle the top with the hot pepper sauce for added heat.
