    Help identifying

    Hi,

    my pond has been running for just over year and it has been rather successful I think. All parameters remain in the correct levels and Iíve had good growth rates.

    One of my fish has developed lumps over the body and I wanted advise identifying what they are so I know how to treat.

    Iíll put pictures below

    thank you for your help.

    Hi all initial thoughts are below


    Hello ,
    I have to make clear that as a laboratory dealing only with fish it is actually impossible to diagnose any disease or condition based on a photograph. I appreciate that forums and web sites make various claims based on limited knowledge and experience that can mislead those who need to know what is wrong with their Koi . For professional and legal reasons we have to explain the service we offer will differ with information obtained elsewhere .

    Based purely on the picture the white growths would appear to be caused by the Carp pox virus and if the fish is eating and behaving normally it is the most likely infection. It is a very common viral disease that breaks out as water temperatures drop . It is not usually a serious disease and as fish mature they develop immunity to it and the white growths will then no longer appear at low temperatures although this will take some time . There is no treatment possible and I would leave the fish alone as long as it shows no signs of being unwell . There are various strains of the Carp pox virus that can make disease outbreaks differ . If the growths become extremely numerous contact us again for advice as this can complicate the disease process .

    Best Regards

    Thanks for coming back with the update fuzzy, much appreciated.

    Fred was right to think carp pox, but think most will agree, it doesn't look like the typical carp pox we are used to seeing so it was great to get that confirmation.

    Nice one fuzzy. For the comeback on the info.
    I thought carp pox on the pink spots.
    But the white ones threw me. And as RS says. They don't look like the normal pox in the photo.
    All the fish I have had with pox. It looks like a jelly spots. That's why I was not at 100%
    In identifying the illness.
    You learn every day. And glad you got a correct answer.
    Age and immune system eventually will make it go away. All the best
    Fred

    One of my koi developed a single carp pox lesion on his lower lip when he was about 4yrs old - none of my other koi were, or have subsequently been affected. For well over 10 years his lesion would ‘bloom’ in cold water and then reduce substantially in warm water temperatures, but never went away completely. This year he suffered an explosion of carp pox - multiple lesions on all his fins, none on his body. No other fish were affected. I kept a close eye on him, and for a while he seemed fine, but then, within a 48hr period, he started isolating and then began to ‘lay over’. I prepared a QT for him but before I could transfer him he died. A scrape taken revealed that he was infested with costia - none of the other fish were affected by costia (scrapes taken), nor, as I said, with pox. So, my take on this is that (a) the explosion of carp pox on this particular fish was due to some unknown reason that affected his immune system (other fish and water parameters fine), (b) the explosion of carp pox basically knackered his immune system response leaving him open to opportunistic pathogens, and in his case, costia basically ‘did him in’ even though I did not have a costia outbreak affecting other fish.

    So, the moral of this message is that yes, carp pox is usually benign, will usually become less of an issue in warm water and may well disappear over time. That said, when your fish experiences an ‘explosion’ of pox be aware that that almost certainly means that its immune system has been severely compromised leaving it open to other opportunistic pathogens. In my case I wish I’d QT’d my fish much earlier, ramped up temperature and kept a much closer eye on how it responded and treated accordingly.

    Sorry to hear of your loss of the fish.
    Heart breaking.
    All the same great information. Just goes to show. We have to keep an eye on them.
    Even with carp pox.
    When all the fish I have had carp pox.
    Touch wood it has not come back. When they have got rid of it. With there own immune system.

    Sounds like your right about immune system making the fish its self. Vulnerable to other diseases. Because its immune system is right down lol.

    Great post Louise and sorry about the loss, but it's very helpful info.

    The other way to look at it is that the unusual extended outbreak of carp pox was a symptom of a deficient immune system that was caused by the Costia taking hold. Either way, the result is the same in that any unusual physical or behaviour changes warrant further investigation.

    Even seemingly minor stuff, for example I have a koi that stops eating below 11C, worried me in the first year but I'm used to it now and ignore it. But if one of the other koi stopped eating below that temp I'd know there's a problem.

    Thanks RS. I should have made clear that when I said that the koi was fine for a while, there was a period of about 8 weeks between the ‘explosion’ of carp pox and the 48hr period when the koi first displayed any abnormal behaviour i.e. isolating then laying over. So, whilst costia clearly killed the fish, given how quickly costia usually takes to overwhelm a fish, I’m doubtful that it played any part in the initial ‘explosion’ of pox. That said, I’ve no idea what triggered the ‘explosion’ of pox and, in hindsight, wish that I’d QT’d the fish long before it began to display any abnormal behaviour.
