    What are these... parasites ? (Mircroscope image)

    So I had a fish jump out of my temporary holding tank on the first night ... and it died! Gutted is an understatement, so I started studying the fish behaviour from the bedroom window... as when I’m next to the pond all they want is food and don’t act naturally. So on doing this I noticed a lot of flashing. I done a few scrapes tested for flukes on week one rescraped found trichodina so treated fmg on the 2 week let them have a week of medicine and rescraped tonight on week 4 and found trichodina again. So my first question is does fmg deal with trichodina well as it states it does but is it the best treatment for this parasite? Also i have attached a few pics of things that I can’t identify within my scrapes I believe the photo listed “a” is a gill fluke but I’m not sure?IMG_0387.JPGIMG_0385.JPG and the other one I wasn’t sure on as it didn’t move at all but clearly looks like something. Thanks IMG_0386.JPG

    Do you mean it's impossible to tell because the photos so small bicolormoth ?
    If you click on the photo you can enlarge it might help who knows.

    Hello mate just checked out the image and if we are both talking about image a then it does look similar to what you sent a link if but you are right I should have mentioned that it had a long body like a fluke where as the one you showed was like a circular shape. I thought it was a gill fluke but there not many images on the web! Don’t suppose you got any idea what image b would be would you ? Ta mate

    Definately flukes but the image is not clear enough to tell if they are skin flukes (gyrodactylus) or gill flukes (dactylogyrus). Image a looks to me to be a disintegrated haptor from a fluke (the attachment disc with the 2 large hooks. On a dead fluke the gelatinous body disappears quickly but the hooks take a little longer to go. There is no scale on the picture so i am guessing it is at a higher magnification than image b. A single treatment should get rid of skin flukes but you will need to do more treatments for gill flukes as they have eggs that will hatch later and will need a second treatment

    Thanks for the response Andrew i has a research online tonight and I’m guessing it must be gill flukes which is a new one for me. Only problem is Iv only just treated with fmg for trichodina so il have to treat on my next water change

    I would say the image of the fluke is a skin fluke as opposed to a gill fluke.

    The reason being that there appears to be an unborn fluke inside of it. It might just be a blob though.

    Skin flukes are live bearers and Gill flukes lay eggs.

    I don't know s

    Treat as though its gill flukes mate. I use ct
    First for mucus. So treat twice.

    Duncan confirmed mine was a gill fluke and yours looks the same

    Both gill flukes and skin flukes have “2 hooks”. The visual differences are that gill flukes have 4 eye spots and skin fluke have a baby developing inside where you can see it’s hooks developing. Of course if has recently given birth, you won’t see the babies hooks. As freddyboy says, it’s best to treat as though they are egg laying gill flukes by treating to get rid of the adults then later once more to get rid of those that have hatched from the eggs.

    That's how I was advised on them a few years ago. On the dotted eyes. But with my eye sight not being what it was.
    If I see a fluke on my scrape I treat as though it is gill fluke. That way your laughing. If you time it right for the eggs.
