I would isolate it from the other fish as soon as possible.
I am certainly no expert but it looks like something I had a few years ago
which I got from a disreputable fish seller and it killed nearly all my
fish.
It is difficult to say it is that but it looks like it.
Mine was an ulceration that deepened and actually ate through the fish where
ever on the fish it showed and the outer coating was just the normal fungal
infection that happens over most wounds like that.
I used an antibacterial and and ante fungal medication but it only worked on
one fish and only then when I administered it topically every day. The sad
side to that was after saving it it went on to live for three more years
before a stoke got him, guess I should have named him lucky.
If you see any other fish getting it remove them from the main pond without
delay, if it is the same thing it spreads like wildfire.
Good luck.
