A popular hack that took the internet by storm a while ago was to use boiling water to separate the fish and the skin. This hack requires a few more tools but is perfect for removing the skin before you start cooking the fish. You’ll need a wire rack, a dish to catch the runoff, and boiling water. Place your fish with the skin side up on the wire rack with some sort of dish to catch the water drippings underneath. From there you’ll boil a small amount of water, and once the water is hot enough, you’ll slowly pour it over the fish.
Let the hot water work its magic for a minute before you start trying to peel. You should be able to see the edges of the fish skin begin to lift and curl up away from the fish. You can then slowly peel the skin from the fish. If you feel resistance, pause and pour more hot water over the skin and resume slowly. This hack is great for dishes that require cubed or fried pieces of fish.
