Genetics is what makes a Koi Angel well... a Koi Angel

(If anybody needs these I will look them up)
Sally Boggs bred among the first and most beautiful Koi Angels. The ones in my album are Sally Boggs koi angels. They are bright white with black on the body and fins with an orange head and red gill covers. The Gill covers are red because the covers are almost translucent and the oxygen rich blood circulating through the gills shows through and makes them "blush"
Now any angel with white, orange and black are called Koi Angels and they are beautiful. Let me show you what the originals looked like

Unless you are going to breed and sell it's probably not necessary to worry about genetics, just that you like it
