Simply Koi and More Koi

One of my Koi has been gulping air and a couple of others seem alittle off. Only this one scape out of 5 did I find anything. It was taken from under the gill plate and I do not have a clue what it is.

Any help would be appreciated

yes this is a nematode a round worm its no biggy most koi carry them just as humans do, these fellows have lost their way they are usually up a hole down the other end

Praziquantel would be my first choice to deal with this but flubenol would probably manage it too
