Simply Koi and More Koi

Hi all. One of my fish has developed quite a number of white pimples on his fins. Pectoral and pelvic fins. The fins look a little off colour as well. The lumps feel hard with some flaky skin, or maybe it was thick mucus which rubbed off.
My temps are currently 15, the lumps appeared about 2 weeks ago when the pond was at 20. At first there was a lot of pimples and some redness. The photos actually show an improvement with no treatment.
scrapes are clear and the fish is eating, maybe some viral infection?

hi

I would keep my eye on this one but for now it looks like carp pox, no treatment available but if these turn nasty it may be something call dermocystidium
but for now ill go with pox

Hi Duncan.

Thankyou for your quick reply.
I will do as you say, keep an eye on it and see how it goes. It has definately improved over the last week or so, which is why I doubted pox, it at first looked quite red with a lot more pimples but seems to be disappering.
Fingers crossed.

Dave

no problem just keep an eye on things and if they get worst report back, but the fact things are improving further suggests its pox
