The fish is a clown triggerfish i thought it made sense since they have thick skin like sharks and sharks don't get ich
i know that sharks don't get ich for sure because all my fish got ich except my lionfish and my banded cat shark
I believe that the lion fish didn't show ich was because they can "shed" their skin like scorpion fish. The parasite could have affected both the fish, but are in the gills of the lion and sharks. If you want to remove the parasite then try to invest or make a fish trap. That way you can catch you fish and Qt them and keep your tank fallow. They may look healthy but a large out break may destroy your tank live stock. This is true for your scopas tang as you said that you did a FW dip and after he looked healthy. This means you relieved s/he of the parasite for a short term. It is still infecting the fish, but not to the naked eye. Now you may follow my advice or not, but this is up to you!
