Please see pictures below. The tang has been in the DT about 2 months and thus far is acting and eating normally. He was quarantined for over 1 month with copper/prazi/metro in a separate QT prior to introduction. I suspect I have ich (likely from not QTing my coral frags) and have been monitoring isolated white spots that have been coming and going on other fish over the past 3 weeks, hoping I can manage with UV and feeding nutritious foods. Is this how ich presents itself on a white tailed tang, or is this something entirely different? From my limited research this is not how regular ich or black ich typically appears.
