Koi in Cherry Groves

I understand that Trails and Tales has already released but I think this would be a cool feature in game. The Koi fish could be a passive mob that spawns in groups of 2-3 in small ponds found within Cherry Groves. They can spawn in multiple different colors. A baby Koi can drop a scale similar to a turtle when it grows, the scale can then be used to repair a small amount of durability on tridents. When the baby Koi grows, it will pick a size to grow into, small, medium, or large. To breed Koi (assuming this is added) you would need to feed two Koi a bucket of tropical fish. Koi can also be a nice way to spice up your gardens or aquariums. I'm sure many players are getting tired of tropical fish in place of Koi. If these were added to the game I would make a huge pond in my garden for them to make my base feel like it's truly home.
