Yellow tang concern (advice strongly needed)

Hey guys i recently bought a great looking yellow tang to be housed in my 75 gallon. But when i put him in the tank i noticed he came with maybe 2 black spots cause at the store he wasnt under lights. The next he developed a skiddish and flashing behavior. He also scatched against the sand as well. So from that point i decided to soak his formula 2 as well as seaweed sheets in garlic. Since the garlic he eats like a beast has shown to start scatching a little less than a few days ago. He seems less stressed and the black dots have seemed to significantly get better. So my question is should i go through the trouble of putting him in quarentine (last resort unless really nessisary) or should i continue to let him settle in the reef and see if he gets better. Can the fish build a nature immunity to black ich and fight it off on its own like ich. Or is this disease diffrent Anyways iam not letting this guy suffer so any help is appreciated.

 

BUMP!!!!

sorry im no help with tangs cuz i have zero experience with them but hopefull someone will chime in on this...

 

I personally since the situation is turning positive for you, with him becoming more healthy and less symptoms of disease. Leave the fish in there and continue to soak foods in garlic and add vitamin supplements such as HUFA and Vitamin C to the seaweed when you soak it.

Works like a charm for me! Good luck!
