Hi JustBecause,

Can you send me a link to a bunch of pics of these wounds?

Be great to have a reference to compare with.

Thanks if you can!

No way you can see this upside down (fresh) pattern once the re-scaling has started. Notice that the pic of the pattern is on a scaleless segment of the fish, near the operculum - probably the only reason it remained visible.
