I was given a large ( almost 24 inches) Koi. It had lost numerous scales
on either side. I believe the cause was trauma rather than a disease
process (there are 2 long lesions of 3 rows wide of scale loss) . I have
had the fish for over a month and it is doing just fine. My question is.
Will these missing scales grow back? Is there anything that I could do
to help the problem? Thanks
