Sarcastic Fringehead (New Fish)

Hear me out, this is a real fish in real life, you should look them up. They live 1000s of metres below the surface and have a unique design that I think would be perfect for Minecraft. They would live in the deep ocean biome and move along the bottom layer. They would be around 1.5 blocks in length and around a quarter of a block wide, and would grey and brown in colour. They would actively look for Squid to attack but do not leave their "territory" which would be 30*30*30 area that they spawn in. If any mob/player enters their territory they would open their mouth wide and inflict it with weakness 2 for every second the mob/player is in its territory. If the mob/player gets too close to them, they would attack it, dealing 5 hearts on hard by biting the target with their huge mouths. They would have 15HP (7.5 hearts)
