I QTd one (my 1st one) a few months ago. Was eating good at LFS so I put it on hold and set up my 20gal QT. After I got him home he ate San Fran Mysis, PE Mysis and black worms right away and then went on hunger strike. After a day or two I got him to eat clam slices by feeding with plastic tweezers. He wouldn't eat from the water column. Another day or so and he was back eating PE Mysis along with the clam slices. Then another hunger strike. Then eating live brine, mysis and clam slices. Then hunger strike and so on throughout first 30 days of the QT. Was very frustrating. I medicated 20gal QT with CP for first 14 days then transferred to new 29gal observation tank with black molly for next 30 days. He was QTd with a second fish, so that may have helped coax him into eating. The last 15 days he ate all the time. He's been in my 220 mixed reef for over a month now and eats three times a day rotating PE Mysis, San Fran Mysis, Hikari Mysis, Live Black worms & Clam slices. He picks at LRS but not sure if he's really eating it. He never took to Masstick. My limited advise would be to make sure CBB is eating before you buy. Have ample food sources and plastic tweezers available before you purchase. I was supprised how many times he would eat from tweezers but not from the water column. If he eats something while in QT, stick with it. (I got smart a few times and would switch up food only to have him turn up his nose at the food he was just eating when I tried another food) Feed three or four smaller feedings a day rather than one or two big ones. I always QT two fish at a time. I believe it makes the fish feel less stressful. My CBB and Moorish Idol always hang out together now even in the 220gal.
