what are the 7 fishes for christmas

It's a tradition in some Italian families to have seven different fish dishes on Christmas Eve, representing the seven sacraments. Each dish represents one of the seven sacraments, and they're often served in a specific order. The seven fish dishes are typically cod, eel, mackerel, trout, salmon, monkfish, and octopus. The tradition is said to have originated in the southern regions of Italy, and it's still practiced today in many Italian communities around the world.
