Hi

Can anyone tell me what this is on my Ogon,it`s pink almost round marks
on some of the scales and does not seem to go away

I have an Ogon that had the same marks on her. I thought it might be underlying ulcers but after a while they all started to turn white and then more white broke through. So if it's the same as what I had it's just discolouration taking place here.

Hi Joe,

If it looks like wax , it is carp pox, if not it could be Dermocystidium Koi

Hi Pieter

Dermocystidium Koi ??? please explain

Joe,

Go to the provided link above, and read all about it!

Costia can also cause red/pink spots on the skin. If the spots are below the skin, shining through, it can indicate the start of a bacterial infection which might be followed by an ulcer.

I would first eliminate the possibility of costia causing the spots by doing a scrape.

It is unlikely that it is pox/papilloma developing now in view of the time of the year.

Hi

It is on top of the skin,but what concerns me is that its been now 3 months
and it does not get worse or better .I am sure that if it was bacterial it would have ulcers already all the other koi are healthy

Hi,

any bets to prove me wrong?

Hi Joe

I had the same pinkish spots on my ogon a few months back it will clear

up eventually. I would say it is pox and you can do nothing about it.

look behind the head. It as all gone for now baybe it will come back in the winter.
