Been treating sailfin tang with cupramine for 4 weeks

To be honest I'd leave it alone. Since the fish haven't shone any signs of disease you really shouldn't have treated them with anything anyway so just let it alone for now.

Well most people say treat as a preventative. Bcuz ich can be in the gills where you can't see it and same with worms in the anthias u can't see them until it's too late

I can't figure out how to edit my last reply.
Not to mention the store seems to have ich in half their tanks. So yea I like to treat preventatively. And I always will from now on. Because I've always bought fish that didn't look like they had ich and would put them in my display and somehow managed to get ich so I'm treating no matter what now. I will not get ich again.
