This is pan frying so use about 2 inches of oil,doesn't need to cover the fish. You'll know when to turn the fish when it's brown on the cooked side and the fish turns white on the top side. I like to use cast iron when I fry,but use what you have.
Chefs will tell you to add additional salt after frying,but I think that just makes food salty,I use additional hot sauce at the table.
This method is good for any fish.I use bread crumbs and the same method for frying shrimp or scallops.
