Using a microscope part 2 - Scraping a koi and finding Trichodina

- This is part two of a two part video this video will show how I go about scraping my koi to try to make it a slightly less stressful experience for them. I tried to show how to scrape a fish but the fish I chose made it a little difficult. Despite the scrape not being the best I still managed to find Trichodina which was a nice surprise.
Keeping koi is very interesting and you can learn a lot about biology and chemistry without being a biologist. Thanks very much Adam for sharing your experience with fishes.
What is it they say, Never work with kids or animals. Great clip as always very clear and informative. Keep up the good work Adam.
Great video. First time I saw how to scrape a fish and look under microscope. I have my 10 in my pond since March 2014 and have never been any issues with them. Just managing water and food and fortunately enough they have very good health. But this video was really great that gave me the knowledge of Koi health management. Happy new year and Thanks
hello Adam
no problem
thank you for getting back to me
as soon as I fill my pond up and get fish in it I will take some readings and see what u think.
my pond is being fiberglass next Wednesday and Thursday.
will keep u up to date
kev
Adam thanks for a nice video, I am just getting into scrapes and managed to do two so far on my little 6”koi. It’s a mmind field of what’s good and what’s bad.
Thanks for the vids! Would love to see scrapes in the scope! It is very interesting for someone like me who does not have that kind of equipment
Hi Adam,
I have gone through all your videos regarding KOI, they were great. Thanks. Please provide a video on KOI sleeping disease (CEV), it will be really helpful for us.
Great vids there Adam thank you. Just bought a celestron after getting sick of guessing what parasites my koi may have when i see them flicking/becoming ill n just guessing with treatments. So i decided to take the plunge n buy a microscope 👍 first scrape upon delivery
Good stuff did you find anything interesting?
@@AdamJulyan I'm awaiting delivery but sure i'll find something. Should have bought one ages ago
Hi Adam
Your videos are so informative. Keep the vids coming . What microscope and camera attachment do you use .
Andy
help my fish are flashing mainly in evening did scrapes on them nothing i can find on microscope
Idk how a towel calms down a koi. But u make it look easy xD
lol i don't either. It did not help that fish too much but the idea is that it keeps the light off their eyes and they don't realise they are out of the water it does usually make it easier also fish are really slippery so the towel helps you hold it. I should have used a bigger towel that could have helped.
Adam
The towel trick is used with wild animals too. Horses and other cattle. The darkness and loss of visions tend to help calm a fish down. I reckon if you placed a towel over the koi, waited five minutes (Air should be enough) then cover it. It would probably be a lot calmer since it will end up in a resting state.
Helveteshit but 5 minutes covering the gills is not the safest.
*****
Oh right, forgot about that part. But was more thinking letting it float above the fish. To submerge it in darkness, much like putting a towel over a bird cage calms the bird for the night. But an airstone with low bubbles below it, should help with the air flow, I think?
Hello Adam
another great video
as I am new to this I have now had my hanna meter delivered from absolute koi over the moon with it please could you tell me what readings I should be getting on the following :
P.H
Ammonia
Nitrate
Nitrite
sorry to bother you again
happy new year to you
best wishes

Kevin, the true answer to your question regarding water parameters is more complex than it seems but as a guide the following should help;
pH - within the range 6.5 to 8.5 with pH 7.5 being more or less ideal (7.0 is considered neutral). pH does vary throughout the day but koi can tolerate small variations (around 0.2). however more than that will cause stress and big swings in pH even within the accepted range is a potential killer - best advice, keep it stable.
Ammonia (NH3) - The toxicity of Ammonia varies depending on pH and temperature (the higher the pH and temp the more toxic NH3 becomes). It's almost impossible to have a zero reading for NH3 but this is what you are striving to achieve. Generally a NH3 reading in the region of 0.02 mg/l (or ppm if you like) is good - more than this and you should consider cutting back on feeding.
Nirite (NO2) - Nitrite is a product of the biological filtration process caused by bacterial action breaking down ammonia produced by the fish. Not quite as toxic as ammonia but don't let that fool you, it will still kill your fish in no time if allowed. Ideally a zero reading is what you should be trying to achieve - if it goes above 0.02 mg/l you need to take action to reduce it.
Nitrate (NO3) - Nitrate is produced as the last stage of the nitrogen cycle by the "bugs" in your bio filter. It's not anywhere near as toxic as ammonia or nitrite but it's not good for your fish if they're subjected to prolonged exposure. Again, it's best not to have any but if you can keep it under 15mg/l your fish will thank you for it (another source I've read says a maximum of 50mg/l above ambient tap water levels is tolerable but personally I think that's too high).
Hope this helps.
@Adam - Another fantastic vid! It's even better because the fish didn't behave for you. Thanks again mate, Keep 'em coming. Regards, M :-)

What is the most common? Should I keep a deletion of treatment I’ve not quarentime tank though?
awesome stuff. 1st time I've seen this process. how often would you do a scrape? is it just a every now and again if you think somethings going on?? or is it when water temperature is at certain level???
Hi, I scrape a fish when i first get them and then if i see any flicking. I will also do a scrape if i am moving the fish to another tank it's best to scrape it first to make sure i am not transffering anything between tanks.
Adam
Thanks for this informative video!!.... I have a very similar Microscope, but would like to be able to re-watch / download what I see. What camera are you using on the eyepiece?
Thanks again>
Hi, Thanks for the comment. The camera on the microscope is a Brunel Digital Eyecam Plus and you can get them from the manufacturer at this link www.brunelmicroscopes.co.uk/cmos.html
Adam
Thanks Adam. Keep up the good work and HNY!
A fish in a towel is a very cute thing.
Hi sir what type of microscope u using
Great videos. Check out my pond and champion koi. You have great videos
One of the koi in my pond has developed some white disks that are sort of clear looking. Some are the size of a dime. Would this be ich? I did several slide scrapes of the fish and looked under a microscope and didn’t find anything. Here is a video of the fish but for some reason the quality of the video is not great when uploaded to RUclips. ruclips.net/video/iHlpWFwH5Bw/видео.html. The white spots are on the middle of the forehead and also on the side gill area. There are also some scales that have the white/clear appearance as well. The fish also has some growths on one of its front fins. It has been more sluggish lately and not quite as social with the other koi and none of the other fish seem to have the issue. Any thoughts?
hi thank you for the help
Hi kevin, sorry i did not reply to your perimater question although airlite x did a great job. On top of what he said if your unsure comment your results and i will tell you what i think. It is difficult to say a range for ammonia etc without knowing anything about your pond as it can vary on the pond and stock levels and time of year.
Adam
dont lift your Koi in the net, it can ruin the fins and break the "finbones"
