Hole in the head disease

[San Diego Joe]

I have a Koi that yesterday looked fine. Today he has noticeable mark on his
forehead that looks like a small crater. Does anyone know if Koi are
susceptible to hole in the head disease? This was the first thing that
popped into my head having had Oscars for some time. This is a rather large
thing though. It looks almost like he ran into something.

My water parameters are very good.

Any help will be much appreciated.

Thanks,

Could a bird have tried to stab it?
I had a egret try to take one of mine and he put a hole in it.

I don't think so. The wound isn't that deep. It looks like someone took a 3"
nail and stamped his head with the non pointy end.

I had this on my koi... dumbass ran right into a rock on a quick turn.
Left a nice mark for a few days.
