I'm new to the hobby with a new tank set up with live rock. No fishes yet, but it's almost time to start adding some. I know the benefits of quarantine to weed out disease, de-stress fish, and help fish acclimate to a variety of foods without competition. However, my LFS says I don't need to QT because their fish are disease free because they treat all their fish with copper. Is this true? And is this a standard practice to treat all fish with copper prior to sale?
