    Unidentified Parasite, maybe Epistylis

    Hi,and HELP Please,
    its been a few years since I have been on the site, but Im loosing fish big time and I need help.
    The problem looks like Epistylis, white patches on the scales, but when I scrape the koi the parasite I see is not what I see in the book or on line.
    What I am seeing is an oval shape, bigger at the bottom and smaller at the top and in side 5-6 small circles and it moves about slowly.

    I have treated twice with Patasium permanagante because when I lost my first fish I saw Trich, but looking at the magic Koi book the dieing koi look like they have Epistylis, so Tuesday I treated with Malgalite green and Formalin solution but toinght another ones gone (thats 12 over three weeks and a few more are looking bad)

    Any ideas? I have tried removing fish and treating with salt but the shock seems to do more harm than good.
    I treated with Malgalite Tuesday so I was surprised to still see parasites when I scraped toninght.

    Im guessing I need to wait until Tuesday to treat again, but I would like to know what Im looking at and if Im using the correct medicine.

    Any help would be appreciated, FYI, I live in Sweden so I doubt if anyone can pop round and help me.

    Thanks, Craig

    Hi Craig, I have zero experience of Epistylis but just had a look at a book and according to that it seems you have already treated correctly with FMG. At the top of disease and medication forum there are some parasite videos and Epistylis is one of them perhaps you could check it out against what you're seeing.

    Good luck, same as you I've lost twelve fish in recent weeks. Very stressful isn't it?

    Hi,
    Still loosing fish, I scraped 3 yesterday and found nothing, I was almost happy, but then tonight found 2 more dead.
    Scraped these 2 and found 3 diferant parasites!
    I have uploaded 3 short clips which show what Im seeing,
    One is very bad quality because I used the camera attached to my microscope, but the other two are me holding my i phone over the microscope and they look better (Ok it was hard holding it still for more than 3 seconds but the picture is clearer)

    I am treating again with FMG, only 5 days since the last treatment, but the fish are dieing so what have I got to loose?
    But What are these parasites?
    Craig
    Im hoping that I have uploaded the videos correctly!! we will see.

    Hi Craig, sorry to hear about your Koi.

    Its hard to tell from the imagines but I would say that............ imagine 2 is skin fluke and imagine 3 is costia maybe!!

    I am seeing still photos rather than video, but agree that 2 looks like a fluke. However if your just finding one fluke then it's unlikely to be the cause of several deaths. Kusuri Fluke M worked for mine (with a dose of PP 24 hours before) on flukes. FMG being more effective on other parasites such as costia, white spot etc rather than on flukes. But you have already treated with FMG and PP Could this be a bacterial problem? Have you checked the gills, are they nice and red?

    Hi,
    I have shown the video of the parasites to a guy who imports fish from Japan and has years of experience and he has seen this before but doesnt know the name unfortunately.
    He said its a form of white spot that is resiliant to FMG, which would explain why my treatments are having no affect, he said he solved it by adding 4kgs of salt per 1000 litres water.
    So tomorrow im off buying salt and by this time tomorrow I will have a salt water pond, My pond is 35,000 litres so by my maths I need to add 140kg salt.
    My plan is to add the salt over 8 hours so not to shock the fish anymore than needed, hopefully the shock wont kill them , but at least I have a plan.

    Can I upload videos to the site? I tried but all I succeded with was thumnails which type of files do I need to convert the vids to?

    It's a lot of salt to mix and dissolve. So good luck, it will probably take at least 8 hours to get it all dissolved! Maybe put half in one day and half the next so the osmotic shock is not to sudden.
    I have seen videos on the site but have not done one myself so can't help with that.

    Had to salt the pond a few weeks ago, I'm a relative newbie. I read that salting will not push a sick fish "over the edge" (providing you don't go near and over the fish's internal solution of 0.9% or 9kg per 1000 litres as you put it) and you are obviously in a hurry to add the salt, so your plan sounds good.

    twokoi is right, it's a real PITA to dissolve. Be sure to check there is no salt lying on the bottom of the pond and that it is all completely dissolved. I was advised to put my salt level to 0.6% which seemed like LOADS of salt.

    Just a thought, if you are doing water changes you don't know the exact value of, you might want to get a salinity meter.

    Also, I don't know much about treatments but I do know that some are incompatible with salt.

    Salt is a favourite of the Japanese breeders I believe and certainly a bit is a good tonic. Was reading that it can be effective at a lower level alongside acriflavine although I’ve never tried it myself. Be interested if anyone else has?
