Salted Anchovies How Long Can I Keep Capers, Olives, And Anchovies In My Fridge Once Opened?

How long can i keep capers, olives, and anchovies in my fridge once opened? - salted anchovies

I bought capers marinated in balsamic vinegar, olive oil, Morocco, and anchovies in olive oil and salt.

I opened all day for food. Now, how long can I store in the refrigerator? Salt and balsamic vinegar work as a natural preservative?

I used to throw in three days, but I have with the salt and vinegar, which should last longer?

Thank you!
