Koi rubbing pond....

Subject: Koi rubbing pond....
by webreaper on 29/6/2004 16:22:31

I've noticed in the last few days that a couple of my young ghost koi and one of my older koi have started rubbing themselves against the side of the pond, almost as thought they've got an itch if you know what i mean.

Is this because they have some sort of disease?

Any help would be appreciated.
