Brownish/Beigh marks on fish?

[L2]

Hey there,

My dwarf angel fish had these small strips of brown/beighe on his forehead two weeks ago. Looked like he had bumped his head against some live rock. It went away — the marks are gone, completely. They were pretty tiny strips..markings... Sort of looked like a scrape. He's fine. They all seem very happy. Now my psudochromis has a smilar patch on his forehead. Did he pump his head too? They swim around a lot. Or is it some sort of small infection? Should I leave them alone or do I need to treat him? Or is it just normal skin that flakes off?

I've attached the best photo I could get. I shot 100... He moves around a lot!! So it's a bit blury. Any advice? Thanks!!

It`s still hard to tell from the pic. Maybe you can get a better one.
