The picture quality isn't that great so I can't see if there is anything wrong.
Can you list the water pramaters?
Size of tank?
How long as it been established?
How many tank mates and what kinds of mates? (you might have said these in another post but I can't remember and it's
always good form just to put this information on any tropical fish emergency post)
What specficly is the damage to the fish? (since I can't tell from the photos)
Is the fish acting an different? Lethargic or hiding or anything like that?
Is there an visible aggression amongst the fish?
