Can you tell me what kind he is? It is the only one that I have ever seen with color and markings like his.. He looks almost fake.. I call him mickey d cause he looks like a painted up clown.
there are lots of charts online that show koi varieties, here's a link to one of them. I would say yours is "showa" but that's described as a black koi with red and white markings, and yours looks more like a white koi with red and black markings.
try google "koi markings" to see lots more options
