I have a CBB in my 120 which was supposed to be a FOWLR but has turned into a bit of a reef...I would say it is a TOUGH fish to get going.
I lost my first one, however I didn't choose the fish-I had it shipped to me...my second one is doing well in my tank but I have to hand feed with a turkey baster and mysis shrimp DAILY which usually takes me 20 minutes or so. It also is partial to live clams (got that idea from a local reefer) that I buy at the local seafood shop, rinse with fresh water and crack open, and thawed bloodworms soaked in garlic and selcon. It has now decided that it will take a bit of fresh scallop when I feed the carpet anemones. Not an easy fish but BEAUTIFUL!
Mine does "taste" corals here and there but I can't say that it has really damaged any. Ate each and every aiptasia though! I haven't put any LPS in though or or course any clams. I do have a large number or Zoos, Button polyps, GSP, some easy SPS, Echino, mushrooms, and 2 carpet anemones.
