In addition to tilapia, you can also include shrimp, mahi mahi, scallops or other shellfish.
This is pretty much the ceviche recipe I used:

Directions
- Combine all ingredients except red onion and mix well.
- Place red onion on top and let it marinate in the refrigerator for at least 2-3 hours before serving.
- Before serving, mix well and serve with lettuce, corn, avocado or other cold salad vegetables on the side.
- It is important to use a juicer that squeezes the juice out of the limes, not one that will tear the membrane of the lime sections since this will make the lime juice bitter.
