There are a couple white spots near Flame Angel’s eye that are slightly raised. Flame Angel arrived 3 days ago (was quarantined), acts normal and swims around rather freely by now though there was mild to moderate fish aggression day 1. I’ve never noticed any ich on my fish since tank was started 2.5 years ago. I assume it’s some lifted scales from some fish aggression toward the new Flame Angel, but please let me know whether you agree or think it’s something else.
