    First scrapes, what am I looking at?

    Done my first set of scrapes today an a health check on a couple of the fish. My ogon and shusui have some sort of fin issue which I have added a picture of on the Ogon. The shusui is without the white on the fin but a bit sore looking so I treated both with ulcer treatment sealed with propolis.What am I seeing in the scrapes though?

    When doing scrapes....
    Make sure you are in a dimly lit room to get the best view of your slide
    Basically you're looking for anything moving but not all moving creatures are harmful
    If you're on Facebook have a look for Shaun Slevin on Koi Helpline UK and he has posted a few times on there different things to look for on a slide
    You want to scrape at least 5 or 6 koi, ideally from the Gill plate down the side of the koi and also on the underside of the koi from the gill plate to the bum fin
    Take your time as there is no need to rush

    If the second slide in the second post of the three was moving that could well be Costia - little comma shaped fast moving things

    cheers

    I scraped 5 of my 11 koi, took me about 3 hours in all checking them over then scraping and looking under the microscope however it was my first time. I did 3 scrapes from gill to tail and 2 on the underside. I couldn't see anything clear other than what I have posted through the different magnifications and all through the slides. I need to get more practise but don't want to keep taking fish out and scraping. I was very thorough looking through the slides and multiple times through each magnification though so maybe there isn't a great deal going on there. although have seen a couple flick and flash, usually the same 2 fish so maybe try scraping them again next weekend and treat for Costia this week.


    Thank you Gaz, I did think that may be costia but as a complete novice it could have been anything too!

    Thanks Andy. I scraped the ones that I have seen flicking/flashing recently as there is only 2, then 3 that have in the past just to make sure.

    I treated with FMG for the costia last night. Will do a follow up treatment on Sunday to make sure after a routine 10% water change. Does FMG do much damage to the filter bacteria? Just wondering more in regards to feeding etc. Fish seem fine with the FMG in the water and acting normal

    I usually stop feeding on the day of the treatment and then you can restart the next day, I don't think FMG has any effect on the fish with regards eating
