    My Pets have pets of their own

    I noticed a the odd koi flicking the other day so I thought I'd do a scrape. I scraped four fish and found multiple trichodina on all for but only only found two skin flukes in total on two different koi.

    It's that times of year again so best keep an eye out for critters people.

    Video taken at x100 via smartphone multiple trichodina flying around like UFO's

    I'll be giving the filters a good clean in the morning ( not that they appear dirty ) and using potassium permanganate. I will be observing the koi for the next few days and maybe another scrape. I'm reluctant to us fluke treatments with so few flukes but will be keeping a close eye as I raise pond temps and koi behaviour.

    I hope this is useful to someone out there.

    There are costia on those slides too I think. Be on the alert!

    Hello Feline thanks for looking. I'm fairly confident that there are no costia. I like to use quite a bit of water on my slids which I guess can make things float about more. Which video do you think has costia in it? I know the quaility is a crap which doesn't help.

    Don't look at the fluke, look around it on the slide for small slightly comma shaped objects with a random tumbling motion. You need to focus on them one at a time as you view the video to see that they are actually alive not floating in a stream of water. At this magnification definitely missable, but I'm pretty sure I can see them. They are more out of focus on the top video, but amongst the mucus if you're really looking. Not a huge number as yet, but you could find them increase in number as temperatures go up so best to be very watchful.

    Hey Feline I just wanted to reiterate to you thanks for taking the time to look and reply. I understand what you are looking at but I believe it's not costia but small particles floating in the water stream. That combined with x100 and me trying to hold my phones lens in focus over the eye piece doesn't help. My method for looking at slides is to do a pass of the slide at x100 and even if I don't find anything that stands out I do another pass at x200 for good measure. I have seen costia before through a microscope and I understand what you mean by the way different parasites move. I did try and do a video at x200 magnification but struggled to keep the phone focus which might at showed the stuff in the back ground better.







    I hope I haven't come across being negative or anything as everyday is a learning day .

    I'm having a purple morning so hopefully the PP will do it's job.

    hah , that's lucky, i don't see any costia but even if there is, p.p is the treatment anyway for trich and costia.
    I had to treat for costia couple months back, i used p.p at normal dose, it was going brown after 3 hours so i redosed at normal amount, and then left it 4 hours before neutralising with s.t, boom...costia was gone !

    Hey David the PP treatment went well today in terms of the koi and the duration. I don't have a ORP meter but it stayed purple/ pink for the full 4 Hours easily. I reversed it with ST crystals at this point.

    I treated at 1.7 grams of kursui potassium permanganate per uk ton of water. The Koi never looked stressed or unhappy.

    I normally treat at 1.5 grams which is widely considered safe but I've been using ST for dechlorination so I upped the dose.

    I don't recommend anyone else does this though.

    I guess time will tell how successfully the treatment has been.

    Hi Adam,

    You say 'it's that time of year again'. I am genuinely interested to understand more behind this. I have read before that spring is a time to be watchful as koi come out of the winter period but I always related this thinking to cold water environments that follow ambient air temperature (so not heated). Is there a specific environmental factor other than water temperature that changes at this time of year and hence can lead to a stress induced parasitic outbreak?

    I am currently heated at 16C and have been all through the winter. All environmental factors re the pond have been consistent for months re feeding / water quality etc. (as I am sure they are your end), hence I am wondering if you / anyone else can share any insight re what factors might lead to such outbreaks in late winter / early spring (particularly on heated ponds).

    Anyway....hope it all sorts itself for you.

    Thanks.
    Ian.

    Hello Ian that question is probably a little above my pay grade to give some sort of scientific explanation. I think most koi keepers experience some sort of parasitical out break in winter/spring even if they do heat to some degree.

    I'm guessing it's more of a trigger in the environment in general that kick starts parasites. Most parasites are just waiting for favourable conditions to take advantage. I believe most koi carry a few parasites which don't cause a problem in healthy fish till a problem arises. Maybe it's not just a temperature related thing but also down to environmental factors such as the amount of daylight strength and number of hours for example?

    Sorry Ian not really much help there for a solid reason.

    Hello David, I haven't done a scrape since because of the weather but they seem loads happier. I've started bringing the temperature up and currently at 15c. The higher temps might kick start anything lurking but I need to spend some more time observing now it's a little warmer outside . I've not witnessed any flicking but it doesn't mean they aren't doing it every now and then.

    Time will tell and cheers for asking mate.
