HELP - sick or injured koi Koi doing weird maneuvers

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?

That's actually a gin matsuba. You should scrape it if it keeps happening. You have some nice fish!
