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.
