I spoke to a koi farm owner about carp pox, and while many people on here will tell you it's very uncommon, I was told that it is more common than people think.
Whether this is true or not, I don't know.
I had a small koi that didn't grow in 3 years, and has what yours has all over it's body.. It didn't go away.. I tried tons of meds, different water temps etc etc.. it didn't work. He eventually died, but I am 100% sure it was carp pox. It lived with my other koi for 3 years, and none of the other koi caught it. But, it can be spread.
Hope you find out what it is.
