Koi Flashing

[Magzire]

I notice one of my Koi was flashing. He looks healthy but decided to take him out and give him a 10 min salt dip.
Then i notice little shiny spots. Maybe he damaged his scales himself while flashing.

I have picture, any idea?

Could be do you see any damaged scales .I know with fish it is hard to see .Has anything changed in the pond and have you tested your water .

No damage scales besides what appear to be scratches if anything. They are not white lumps.
As for changes, there is a few. Added 4 more fish (gave them salt dip before adding) and also placed a new raised pond (6x6ft, deepest part is 4ft) over the existing pond. Also added more filtration, a pressure filter and a new 70 litre DIY container.

I only have a ammonia test which reads the lowest and i have a bunch of hornwort plants (also new) with 30% water change weekly, also 0.1% salted.

It is not unusual for Koi to occasionally 'flash'. It is when it becomes a frequently occurring behavior, usually involving more than one fish, that closer investigation is warranted.

All plants and all fish should be watched for at least a week or more outside the pond .I clean and repot all plants ,you never know what could be hiding in the roots .
