So I got a purple tang from a very trusted lfs. I've tried Ttm but it's very labour intensive so I'm going to try copper. However my lfs that I trust runs full copper and prazi and hypo. When I bring home a fish that's been there for 2 weeks under this sort of treatment should I continue that when I get home meaning dose my qt with copper or should I just observe from this point on to see if I see signs of disease etc until I put him in my dt?
