my butterfly koi is 55cm and eyes have sunken in ,help plz

Two things comes to mind. Gill rot or KHV.

The first step would be to inspect the gills. See if they look healthy. Are there any other signs, for instance lethargic etc?

Can also be costia or a bacterial infection.

If the gills look fine, do a scrape to check for costia.

There is also a condition known as pig eye where the bone around the eye grows and starts to cover the eye. That can also cause they to look sunken.

ooh, ooh. Adeel how many fish do you have and please until this is resolved dont move any in or out of your pond. This does not sound good to me where are you situated? Are you a SAKKS member? I think you should call them if you are. If you tell me where you are I will tell you where to have a KHV test done.

HI NEVILLE IM IN VRYBURG NORTH WEST PROVINCE. I HAVE CLOSE TO 40 FISH RANGING FROM 6CM TO 50CM . ABOUT 33 LESS THN 15SM AND ABOUT 7 BETWEEN 30 AND 50CM. IM NOT A SAKKS MEMBER.

Hi Adeel,
Thanks for the info, I realy dont want to run away with this but the symptoms is related to KHV as well as others which I do not know. When last did you add fish and from where did they come? Sorry for all the questions. I am just trying to get some background. I am seeing someone tomorrow that could also maybe help here, Please dont panic I might well be completely wrong. Let us see what the other forum members think tonight and take it from there.
Please take care will let you know.

I cannot comment on anything else but this ... that fish looks particularly thin to me .. almost as if it starved.

Looks like gill rot.

Symptoms of gill rot:

Sunken eyes
Discoloring (see the grey spot)
Section of the gills missing
Filaments appear to stuck together
Fish lethargic

Gill rot is caused by either KHV or Flavobacterium columnare or in short Columnaris disease which is a bacterial disease.

It can also be caused primarily by parasites that goes over into this type of secondary bacterial disease. Is it you you phoned me about fish lice and ordered Dimilin from me?

If any of the other fish are affected, you should take a swob asap and send it to MDS in Durban. See the procedure and application form under the KHV heading of this forum.

Please keep us posted.
