If your tank doesn't have much fauna for your CBB to hunt, then you must remove the aggressive fish so that the CBB can eat in peace when you are feeding the tank. In my 320 gal tank full of worms and aiptasia, and my CBB pair eat aiptasia, I released them into it and they did fine. There is a large 5-6 inches Powder Blue and Purple tangs, small Harlequin Tusk, 4 inches Desjardini and a 3.5 inches 3 spot damsel (the resident jerk) My CBB pair did fine. I make sure that they were eating well and was eating all the aispasia in my QT system. My DT is full of aiptasia. They essentially have unlimited food everywhere so even they got chase for about 1 week, they are always full.
My situation is unique (IMO). You are going to have to be really careful and watchful. I would not release the CBB until it is eating really well and fat, and you have way to feed it without been excessively bother by other fish.
