Ceviche Variations. Ceviche is usually made with sea bass or flounder, but just about any fish or shellfish will work. The other ingredients vary widely. Ecuadorean ceviche is often made with shrimp and ketchup in addition to the lime juice and served with corn nuts. In Chile, ceviche is made with Chilean sea bass, grapefruit juice and cilantro.
The discussion is mixing two different issues. The question is about keeping ceviche in the refrigerator (retarding bacterial spoilage), not about parasites in the seafood, which are (a) never safe, (b) not going to get worse, no matter how the ceviche is stored, and (c) not an issue if you buy the right kind of fish. Ceviche is made with the juice of lemon or lime.
