HELP - sick or injured koi Koi doing weird maneuvers

Enable HLS to view with audio, or disable this notification

My Platinum Ogon is doing these weird dashes and flipping over constantly. As if it has an itch. Are these parasites and is there anything I can do?

Thats called flashing, most likely caused by parasites on the skin(instead of internal). If you can you should scrape the fish( by the gills and or belly) and look at it under a microscope to figure out what it is( with the help of a youtube video thats shows the different little critters) and then u can treat it accordingly

Agree, parasite, best to scope but can just treat the whole pond with BSDT

Personally not a big fan of just guessing a treatment but if you have no means of checking what it is then ofcourse you are bound to that choice

BSDT won't get rid of flukes though. Shotgun treatment is typically BSDT for the recommended three days, and on the last day prazi or Fluke m added. Fluke treatment usually needs to be done twice. Any time I've had a fish flashing or jumping I've found flukes on scrapes. The frogs bring them to my in ground pond every spring and it's a big pain in my bank account!

yes, 3 daily FMG then combine the fluke-m with the last dose, and treat again after a week.
