Hi again quite a few of my small koi have been getting these disgusting holes in them but do not actually die from it but keep on feeding and swimming around quite happily. Of course eventually they do die or unfortunatley I have to intervine much to my sadness. I have visited my local supplier who took a scrape but found nothing. He suggested I try a remedy called Combat which he supplied me with I treat the koi with this and it was ok for a few days then the sores started appearing again.My water parameters are all spot on. I have some larger koi in a larger qt but fed from the same filter so far only one has suffered this appalling condition during the cold weather the qt's were heated to 19- 20 degrees. Can anyone help as this is driving me mad .

hi paul , from what ive seen , its hard to tell the difference between new hole disease and ulceration .

the only thing i think you need to do is treat this fish like it has an ulcer , that looks bad !!

i hate to say this , but your two options , one is ....... you know what , the other is treatment .

if you choose to treat , you'l need to set up a quarantine tank which is heated , use salt and proflavine hemisulphate or salt and acriflavine .

next you'l need to find the cause of the problem , as i said its hard to tell the difference between the two . so a full pond clean is in order also check all you filtration , pump turnover ect , and mabe even pull all the fish out and do a deep clean .

unfortunately , if it turns out to be new hole disease , its viral so you could be doing it all for nothing .

i'm really sorry i don't have a solid answer and cure , but with the possibility of dealing with this new virus , hard facts and cures are hard to find .

Hi Paul, I had last year 2 koi with identical looking ulceration. Treated with anti ulcer which seemed to work for about 2 weeks until things got worse again.I lost the one koi but the other was still eating so I decided to give it a chance. I sedated the koi, cleaned the wound with malachite green and sealed it with propolis. At the time I did read something about a gel you can get in the pharmacy. Its used for human mouth ulcers. Thought I give it a try, after only two days the red hole was closing with white skin and the koi was much happier. The red edges struggled to heal a bit. Think i should have removed the lifted rough scales much earlier than I did. Once the whole area was covered with nice skin I went back to treat the wound with malachite green and propolis once a week until there was no sign of infection or open wound left, just to be sure. The entire whole did heal and fill up, could'nt belive it by myself. Even the scales started to grow back now. I think the gel has worked really well, only thing is it does'nt stick as well as propolis.
I hope this helps and I did'nt tell you anything wrong but I thought it might be worth mentioning as it worked really well for my koi.

hi paul , the dose for pp , is 1.5 to 2 grammes per 220 gallons

you need to know your pond volume to the nearest gallon !! also have loads of dechlor on hand to neutralize the pp , in-case the fish start to struggle , also you'l need the water to turn pink/purple for X amount of hours , the reason i say X amount is pp is a good parasite treatment , and the treatment time varies dependant on the parasite being treated .

pp , is an oxidising agent , my worry would be your treating koi with open wounds , if these wounds are deep , deep to the point of exposing internal organs , the pp will affect them .

you still really need to do a scrape , to see if it is a parasite affecting the koi , that has caused a secondary infection , if you do a scrape and find parasites , then you could ... to a certain degree rule out new hole disease , and be pretty sure your dealing with a ulceration and bact problem .

if you can pin it down to this , proflavine hemisulphate , acriflavine , fmg mix ect would be a better alternative than pp

Hi again I havent added the pp yet I am planning to have a go tomorrow so that i can monitor it I only have 1 koi at the moment with an open wound but it is quite severe.I have had scrapes done but with zero results.
I think I may have started the problem having read other articles by heating the water to 20 degrees and keeping it at that apparently according to the fish helpline this is the ideal conditions for bacterial manifestation. The only reason I am trying the pp is that to be quite honest i am at the end of my tether with it I hate to see these beautiful creatures suffer.I will update Shortly.
Thanks to everyone for there kind advice.
Paul
