Sheol is correct, that is a beautiful fish, but a common color variety as far as aberrant colors go. If you want to see some really different colors look up the St Paul's Rock queens. St Paul's Rock is a small group of islands off the coast of Brazil and the queens there are so different, some are colored dark blue, almost navy blue, others are pure white or white with black spots and the best ones are koi colored with 3 or 4 colors such as white, black, orange, and blue all mixed up like a freshwater koi. Really fascinating fish and genetics involved.
