Hi Paul,
Sounds like fin rot which is a bacterial infection, this is usually a sign that your Koi is stressed.
You need to find out why your Koi is stressed, double check your water parameters, have you changed the enviroment of the pond over the last week or so ?
Sometimes finrot is a secondary infection, the fact that your Koi is lethargic is not a good sign, it could indicate it actually has another problem that has stressed the Koi which has caused finrot.
Is the pond heated or unheated ? are the other Koi lethargic ? what size is this koi? are they in salt at all ?

hi extreme thanks for the reply
the fish is in unheated water but indoors water temp runs between 12, 15 c
it is not in salt , all parameters seem fine i checked again this morning and will check again tonight ,the fish is 15 inch the tank he is in a 9x6x3ft along with a 16 inch shusui that seems fine .the asagi did have pox about 10 weeks ago and wondered if this has had any secondary effect on the fish i did do a partial water change 3 days ago but nothing out of the ordinary.he has been fine untill the other day and yestsrday he started to get lethagic . thanks for your help .paul

The fact that he is lethargic in water of that temperature concerns me to be honest.

You need to get a scrape done to find out what is stressing him, salt will help with the finrot, but I dont think thats your main problem.

Id get the scrape done a.s.a.p, could be parasites.

Sorry I cant help any further Paul, Good Luck!

thanks for the advice extreme ,the scrape sounds like the only option really.how much salt per gallon would you recommend thanks alot .paul

1/2 ounce per gallon, but make sure you get the scrape done m8.

hi extreme
his going for a scrape tomorrow ,but he seems a lot less lethargic .my nitrite has also climb over the last couple of days so i added water cress to my filters on thursday and this has seemed to have a positive effect, so fingers crossed he will hopefully be clear of any parasites .thanks for your help with this, the next time im in london ill come out to essex and spend some money with you (but dont tell the wife lol ) ;D thanks again. paul

High Nitrite will cause stress and will be why the Koi have developed finrot, this will also make your Koi flash or rub..............Dont feed at all until the nitrite is down to zero.

Good Luck......

i held off the feed since thursday and the nitrite has been coming down over the past couple of nights. just goes to show how inaccurate chemicals can become over time

.maybe ill replace all my test chemicals just to be on the safe side. thanks again paul

hi extreme had the scrape done today good news no parasites must be stress from nitrites. would you reccomend treating the fin rot or leave it up to the salt. also is there a chance of the fin growing back or will it stay as it is . thanks again paul
