Hello and welcome!

Please tell us some more information about your pond. How is this fish acting and how long has this been there?

• Size of your pond
• Number and size of fish
• Type of filtration
• How long has this pond been up and running
• Have you recently added new fish
• Do you test your water and if so, what are the test results

Great picture of what you want to know about. Welcome to our group!

I can't help, I have never had koi in my pond.

could it be anchor worm

 

[ShawnInfirmity]

I wouldn't think anchor worm because I don't see a clearly defined attachment site. The anchor worm usually leaves a pretty obvious red/bleeding wound where it attached to the fish. Perhaps another type of worm though??

Looks like the site of a scale that's all.
The koi remember is a varient of the doitsu it may not have scales but it's still a doitsu.
So nothing to panic about
