Help me ID the spots on my Tang

[Connie]

Below I have attached several shots of my Sailfin Tang. The first pics are to show how healthy he is. The last is pics of spots that showed up on him this afternoon. He and my Scopas Tang have been bickering a little, so I am thinking it may be where this Scopas' scapel stabbed him. It looks like burns. The Scopas nor any other fish has these spots. I also need to mention he is acting completely normal and eating normal. I hope it isn't a disease, but need opinions from others that may know exactly what it is. Thank you!

wow, really looks like burns. possibly battle wounds from maybe scalpel and banging the rockwork or a piece of tank hardware (such as heater)? maybe bacterial infection on the wounds?

The heater is in the overflow, so it couldn't be that. I'm at a loss.

OK. This is getting even more weird. Here is a picture I just took of the tang and the spots are almost totally gone in less than three hours!

Probably just a bruise
