Sea Life for Ponds, Lakes, and Caves

      The oceans are very lively and have many mobs but the rivers and lakes seem plain with only Salmon and kelp, there should be other mobs that come to these bodies of water.

     Kois live in ponds and lakes, they have 3 hit points but don't drop anything. They can be placed in buckets.

     Goldfish live in lakes and rivers, they have 3 hit points but don't drop anything. They can be placed in buckets and tamed with kelp, after taming them, they can be placed in fish tanks (crafted by 9 glass blocks).

     Crabs live in all bodies of water and will pinch you for half a heart of damage if you get too close. They have 4 hit points and drop Raw Crab Legs (gives 3 hunger bars) while cooked Crab Legs will give 4 hunger bars. Red crabs live in or around freshwater, Yellow Crabs live in oceans and beaches, and Beige Crabs will live in cave water.

     Cave Fish live in bodies of water in caves, they're blind and can't see. If they're near you and hear you or something hit the water, they'll swim in the other direction. Trying to catch one might be difficult due to them running away from any extreme or unexpected noise. They have 3 hit points, drop raw Cave Fish (recovers the same amount of hunger as Cod), and can be placed in buckets.
