Koi Fish!

I think Minecraft should add koi fish ponds that would be found in the new Cherry blossom biome, I think they should have many different varieties and patterns and that they breed on their meaning if you want a specific pair to breed you haft to put them into there own little pond I also think they should lay eggs in the water. They should also have different life stages Dutch as being a baby where you can't tell what color they will be to small to medium to large (they should also take a long time to grow)
