gavin.starr Posted August 16, 2009 Share Posted August 16, 2009 basicaly about a month ago i built a new pond, i used to only keep goldfish in the old on, but i decided to get some koi in there as well. the pond is well within the sufficient size L 3.5m x W 2.5m x D 1.5m so it is plenty big enough. i keep the pond well filtered and the ponds water is circulated every two hours through the filter and the UV bulb. over time the fish have developed the waxy looking scales and one is worse off than the others as it is starting to effect the fins and guils too. i have been able to get them out today to take some pics. if any one knows what is wrong could they please let me know as i want to get them back to a good bill of health asap. http://farm4.static.flickr.com/3520/3825589563_5de830e1d7.jpg http://farm4.static.flickr.com/3541/3825594081_80a222852a.jpg cheers in advance gavin Quote Link to comment Share on other sites More sharing options...
SimonT Posted August 16, 2009 Share Posted August 16, 2009 But apparantly when they spawn they get a protective coating over their scales, if its not that its called Carp pox, its from transferring ill fish and there is no cure for it because its a bacterial infection. EDIT - can see the pics now Quote Link to comment Share on other sites More sharing options...
Frank Bullitt Posted August 16, 2009 Share Posted August 16, 2009 Looks like it might be bacterial, I heard of a treatment you can add to the pond water if it is but cant find out more until Im in work tomorrow Im afraid. Any more info you could provide would be useful. Is it definitely their scales & not some parasites? Quote Link to comment Share on other sites More sharing options...
Ewen Posted August 16, 2009 Share Posted August 16, 2009 It certainly looks like Carp Pox to me. There is a lot of information on the web about Carp Pox...I suggest you read up on it as much as possible and get specialist advice, but there are a couple of basic facts (only what I've read myself) about it... It will spread rapidly in crowded ponds. It is not generally life threatening to otherwise healthy larger fish. It is however, devastating to young fry. Warm weather seems to help in lessening the effects. Large Koi (15 inches and above) have by then developed a good enough immune system to avoid Carp Pox symptoms, although if they have ever had it, they will carry the virus for life. The visible signs usually disappear over time. There is no treatment...although there are some so called cures on the market, non will work. DO NOT try to remove the waxy spots yourself, as infection will get in to the affected area and you will lose the fish. I'd also suggest you take the photos and a sample of the pond water to an aquatic specialist and get it analysed...even though its a big enough pond and there is filtration set up, Koi are such specialist and sensitive fish they are a mare to keep. Even a small fluctuation in temperature or water quality will stress them out and reduce their immune system to the point where infections and viruses can spread throughout them very quickly. A water sample may point to an area that can be improved if nothing else. Quote Link to comment Share on other sites More sharing options...
Tricky-Ricky Posted August 16, 2009 Share Posted August 16, 2009 Carp pox is usually just the odd lump or two, that looks bacterial to me, and at a guess i wold say do some checks on your water conditions,and treat accordingly, i would suspect that the filtration is not working properly despite the turnover.

R Black Posted August 16, 2009 Share Posted August 16, 2009 Good luck with your koi fella, cant add anything on the ailment, as im a koi noob, only been keeping them just under a year, they are easily stressed. Quote Link to comment Share on other sites More sharing options...

Ewen Posted August 17, 2009 Share Posted August 17, 2009 There you go...three different opinions already. Please get some expert advice before treating your fish for something guessed at on here.....for instance, you dont want to mess with malachite green etc unless you are 100% sure what disease you are dealing with and 100% sure of how to use it. Let us know how you get on. Quote Link to comment Share on other sites More sharing options...
