Flamefish

Flamefish are fish that can be caught when fishing in lava. They also appear as mobs like the other fish. A normal fishing pole pole doesn’t work, so how could you fish them? You can eat them, and they restore all of your hunger, the problem is that when eaten, they light you on fire. They can be surrounded with gold nuggets on a crafting table, and then when eaten, they give you fire resistance for 1 minute.
