    Parasite after parasite!!

    Hi all

    is it common to treat one parasite and then get a different straight after!? Pond been up and running since may and since November, I’ve been dealing with parasites one after the other. Started with flukes, so treated with flukesolve plus which shifted them after two doses. When scraping to see if they’d gone I then found chillo. Two doses of FMG at duncan griffiths recommendations, I then scraped and found costia! (Was possibly there with the chillo but probably missed it) another two doses of FMG and costia has seemed to go, but now have flukes again!! How did they manage to take hold with the FMG in the pond! It’s driving me mad and a small fortune. Just treated with Lernex pro, but hope this isn’t a vicious circle where costia or chillo will come back again afterwards… or possibly white spot! Anyone experienced this?

    I had the same problem, fish jumping flashing and not eating. Last week I was advised by the owner of the local koi farm here in Phuket Thailand to add salt to a salinity of 0.5. We had a long talk about it because the volume of salt he wanted me to add was 60 kilograms which scarred the crap out of me. I used the Koipan calculator and right enough it showed roughly 60 kilograms of salt so over the last 3 days I added the 60 kilograms and the fish are fine. No more flashing, jumping and there back to eating like there starving.
    I will not add anymore salt, I will just let it slowly drop back down to 0.1 (I have a small water leak in my waterfall so that will help to slowly dilute the salinity) and maintain that 0.1 number

    why add salt!? That will need some serious water changes to get back down to 0.1 over a long period of time….

    It was recommended to me to add the salt from the owner of a koi farm here in Phuket. I added the salt and the little bas***ds have gone and the fish are happy once again.
    As far as water changes are concerned my leaking waterfall will take care of that over the next 3 or 4 months.

    Ndw ... Words of caution only as I do hope salt has done it for you but I've just had Fluke and Tric survive 2 weeks at 0.63% salinity in my hospital tank, its deffo not what it once was when it comes to parasites. May well be worth a few extra scrapes to be sure its done it for you.

    Thanks a lot mate. Adding all that salt scared the crap out of me. The salinity is slowly dropping every day and the fish are no longer flashing or jumping. I’ve never scraped a fish so don’t want to go there as I wouldn’t have a clue what to look for even if I did try it.
    When I look at them swimming in the pond without a care in the world, eating well that’s good enough for me. The guy from the koi farm mentioned that it needs to be at least 0.5 so I’m sure what you say is correct. My water temperature year round is 28/30c so that might have something to do with it

    But Neil without an initial diagnosis you don’t know if you even had parasites? Could be many other causes of that behaviour, and the treatment for different parasites different, and pretty much none would be killed by salt anymore, certainly in the U.K.

    But good if their behaviour is now better good info here on how many water changes it takes to remove salt https://www.google.co.uk/url?sa=t&rc...jkPZO_dCv0jfAw

    Thanks for the info...........my plan is to maintain about 0,1 % salinity

    Never had to deal with parasites before. But last year I bought some fish from people closing down their ponds. Both lots were scraped on arrival and one lot has fluke and costia and the other lot costia and a small showing of white spot. I think I've been bouncing between FMG for the costia and Fluke M / Fluke P for months now and whilst I'm down to a very small amount of it I still have fish that have suffered and are recovering. Until it's 100% gone on the fish in the QT, I won't move any of them to the main pond. When it has all finally gone, I should be able to reduce the QT down to just the fish that are still recovering from some pretty horrendous infections!

    I need to post a thread about it at some point, but I have struggled to find the time to keep up with the excessive water management and treatment as well as work and everything else! Just thankful that this has been managed in the QT at 750 gallons, although I have way too many fish in there than I should, but until they're sorted they're not moving!

    Bizarrely I've then had fish in the main pond (11,000 gals) start flashing over xmas (heated to 18C) and have also detected a small amount of costia in there which was treated and then following that flukes (which weren't present on the previous 3 fish scraped) and then once that was sorted, back to costia again!

    So what I am learning is that as others have found over the last year, the standard treatments are not as successful in a single or even dual application that they appear to have been from other users previously. And also that even though you think you've got rid of something, you really need to scrape a lot of fish and probably over a number of days to be sure the parasite has properly gone, as it only takes a small amount to be hiding away somewhere and then in a couple of weeks they can be back again in numbers..

    In short, yes this is extremely common in a new pond. For the first couple of years a new pond is still developing biofilm on all surfaces, and so water quality tends not to be stable and resilient to treatments etc. yet. If you add in the inevitable new fish we all tend to buy when a new pond is finished, you have the perfect storm for parasites to take advantage.

    There is a tendency for koi keepers to expect a parasite once treated to be completely gone, never to return. But the reality is that all systems will tend to have very small numbers of parasites present at all times, just waiting to take advantage of any weakness in pond hygiene or fish immune defences. You also get the situation where existing fish in a pond behave a degree of immunity or tolerance to the strains of parasites present, but a new fish coming in can succumb, or vice versa when the new fish bring in a strain your fish have not encountered before.

    What you are going through is very common, but the good news is once your setup is more mature, it is possible to get to an equilibrium where parasite outbreaks are rare. Be careful where you add fish from though.

    Do you think it would be ok to mix lernex pro and flukesolve plus for a second dose of fluke treatment? About 70 ml short of lernex pro but have enough flukesolve plus left over to make up for lernex (with the adjusted dosage rates) or should I just be safe and buy some more lernex?

  16. #12
    No I would not do that. I have used a full dose of one followed by a full dose of the other a week later though.
    Fighting flukes is an expensive occupation. I always do three rounds.. Lernex Pro full dose 7 days apart X 3..

    I would also say getting rid of flukes in cold/cooler water is hard. Below 18c, if there are lots of them and your fish a visibly ill I would be tempted to hit them with a single dose to thin them out and return with a full triple dose in the spring. As you have put in a lot of chemicals recently you have some thought to stress your fish are under from all the treatments. Sometimes you have to take it slowly. In cooler water say 12c parasites multiply more slowly, So it may be wise to take a pause and come back with a full plan of attack in the spring. Be guided by the behaviour of your fish.

    Thanks Scaly Bob. Scraped my fish today to see if any flukes remained after first dose. No flukes, even though there was gill flukes along with skin flukes originally so expecting another outbreak soon. Did find Costia AGAIN though! Wonderful
