How long does ceviche keep? We just made ceviche with ahi tuna, lots of lime juice, avocado, onion, cilantro and jalapeño. It's wonderful. Unfortunately we made too much. Now, I've never made it before and want to know about how long I should keep it in the fridge, if at all?

Note: this is not super high quality sashimi grade fish. Nor is it the freshest fish in the world.
Drain as much of the "cooking" solution (lime etc) off as possible, and store separately

Both parts will keep a day or two

After draining you can briefly rinse the fish to stop the "cooking" process, otherwise it may go a little mushy, but not unappetising
