This dish is more a salad than a tiradito, although it has the flavors of one. For ceviche, the fish is always used raw. For those who prefer cooked fish, here is an alternative with all the flavor and appearance of a classic tiradito.
Always use limes for ceviche and tiradito recipes, since its flavor is the most similar to the original. You can play around with the other ingredients. However, the basic and most important ingredient, because its acidity marinates the fish, is lime.
