Help! Found some white spots on my blue tang after giving her a fresh water dip to treat something unrelated, however while paying extra attention to her the last two days since the dip as she had a burn I noticed some spots today. On closer inspection I saw some on my royal gramma who is the most recent addition to my tank and if it’s ich I believe he is the culprit. I also may have seen just a few spots on my fairy wrasse but am unsure. Can anyone confirm and tell me what I need to do to treat?
