I got my AT from DD and QT'd in a 40gl long for a couple weeks with cupramine and 8 days of prazipro. I found he wasn't too fond of nori during QT. Totally ignored live caulerpa. No interest in mysis. I fed him live bloodworms, live clams on the half shell. After a couple days, he started eating NLS pellets, and the rest was pretty easy. Never skipped a beat when i started up the cupramine. My QT had live rock, a sump and a skimmer, and a couple maxijet powerheads. I also had an aquaclear hang on filter for further water movement and filtration. Lots of oxygen and some hiding places. IMO you QT for long-term health, as AT's are ich magnets, why take the chance?
