I believe that one of my fish kids has Koi Pox. It certainly looks like it from what I have seen on some websites. I have read conflicting statements about it. It's a herpes virus, so it's obviously contagious. I read on one site that many fish are immune to it. Is this true? Does anyone know or have first hand experience with this? I would hate to see the rest of the gang get this but I also don't want to destroy this guy because I am quite fond of him. I also imagine that they have already been exposed anyway, so it's probably a moot point.
Also, I've had these guys four and five years. I got them in a couple of different batches when they were just an inch long. Would this fish have had the virus since I have had him? If not, how else would my pal have contracted this disease?
