No fish goes into my DT without going into my QT tank first for about 8 - 10 weeks. 2 weeks observe fish, make sure it eats, then Prazi 2x treatment (about 2 weeks) then start 6 weeks copper treatment. The one thing I wish I knew about this hobby is how quickly things can go south fast when you put a sick fish in an established tank. There is only one place I trust to quarantine their fish and worth the extra money, that is TSM. I am lucky to have them fairly driving distance so I see how well they take of fish and strictly quarantine.
My advice... if you have the room, set up a QT. It is so worth it! it's a pain yes, just another tank to take care of but when you put that fish in your DT you will be confident that it doesn't have any parasites. A few months ago I purchased a Gem tang, 4 days in my QT it broke out with Ich - immediately treated - now it is doing great in my DT. I have a regal in my QT now - noticed it was acting strange (twitching head), sign of flukes. I started treating with Prazi and already showing improvement. Just some examples. I think most fish you buy these days will have something.
