Water Temps are in the high 30s, most of my other koi are doin fine but today I check on the and noticed one of them acting strange and just laying on the bottom so I picked him
Up and noticed this. Any clue
What it is?

[Jeff Zimnisky]

Just tagging a few knowledgeable guys who may know.

It looks like mouth rot, or an ulcer, however I don't have treatment information. I'm sorry

 

[Jeff Zimnisky]

Too late, he's gone. Shit he went down hill fast. Rip

 

[Mike in Vermont]

Sorry for your loss.

 

[addy1]

It did look bad, no clue what it could be. So sorry it died.

 

[haver79]

Sorry you lost him. I have no clue. Hopefully someone can figure it out.

 

[j.w]

Do you think he had it for quite awhile and you just noticed it since he started acting ill? Doesn't look like something that appeared overnight. Sorry you lost him. Now hope you can find out what it was in case it's contagious.

 

[Jeff Zimnisky]

I haven't noticed it but im sure it didn't just happen overnight.

I'd say (from the picture) that it's mouth rot from flukes. You'll need to treat the entire pond, or risk losing more fish.

Try Praziquantel . You can find it on-line.

 

[Priscilla]

So sorry! So scary that it just happens! Where in the world did flukes come from????

 

[Jeff Zimnisky]

Even in 30* water?
