Possible ICH in Similar Damsel

[ILMT]

I noticed some pale white spots on my Similar Damselfish. My first thought was ICH but I'm not too sure. There's a possibility that they might just be wounds from his fights with the other fish though. Should I presume it is ICH? I'm going to transfer him to a quarantine tank tomorrow to be on the safe side. I'll take some photos too while I'm at it.

History of fish? Quarantine? Other fish?

[ILMT]

The other fish I have are a pair of Black and White clowns and a Scopas Tang I adopted not even a week ago. The damsel has been with me since 2009 and hasn't presented any problems until aside from the occasional fighting with the other fish.

If the other fish were not quarantined, it's possible one of them introduced a pathogen. Pictures would be helpful for diagnosis.

So when I took my damsel out to take some photos I could no longer find all those spots anymore. Anybody know what's going on? they were a few days ago.
