New Mob Idea: Soulfish

Hello! My nephew loves Minecraft and has his own special new mob he would like to see in the game! It’s called a Soulfish. It is a prehistoric cyan fish like creature with a black skull pattern on its tail fin. You find their frozen eggs in ice blocks in the ice biome. To hatch one you must melt the eggs from the ice with a soul fire, then put the thawed eggs in the water where four fish will hatch. They can be tamed with pork and only attack the player when hit. They are 1 block small.
