I only had a clown fish and no coral in my tank and decided to add a tang. Since my tank was new any I only had a clown I added the tang directly with a blenney to the tank. After a couple of days the tang started showing spots. I scurried down to the LFS and bought non copper ich treatment. Within a week the tang was a floater and the clown was showing spots. I switched to a copper based ich treatment and the ich seems to be under control. No spots on the clown and the Blenny is fine.
Lessons
Always use a QT tank regardless of what isn't in your tank. Treating 200+ gallons is very expensive in comparison to 20 gallons.
Non copper based treatments do not work very well in my newbe opinion. I would have a whole lot more issues if I had coral because I understand coral is not copper tolerant . My snails had to be moved to the qt tank until treatment is over.
As stated thousands of time on the site, qt and be patient.
RIP - bobby the blue tang

I would run copper absorber for quite some time. Thanks for posting for new reefers. I'm sure it happens more ofter then people realize.
