Rework for fish mobs

  Fish mobs are currently pretty easy to catch with a water bucket, it should be more realistic
  Fishes now run away of the player and non aquatic mobs when near similar to how ocelots, cats and foxes does, but only if that other mob is in the same water as them, with a greatly increased mobility, being able to quickly escape from them player
  Fishes can be attracted with seeds and food items dropped on water, but they will still flee from the player, they can also be pushed using fishing rods, which would be the perfect oportunity to catch them
  Other pacific aquatic mobs such as sea turtles and squids wouldn't mind the player, but run away if attacked, and fishes would still behave the same outside water
