I have had a few but my “winner” ended up being at the LFS for 3 weeks before I decided to give him a try. I had sworn off of them tried 3 times before would make it weeks if not months then one day would stop eating. The one I have now and have had for a while was housed in a tank with a 5 inch purple tang and 7 inch Naso and was out competing those two for food. That was the deal maker for me. Each individual cbb is different as others have said. Mine doesn’t mess with coral at all but is a clam killer, where as others I have had before left them alone. He made short work of a 7 inch maxima

the only positive of that has been when he decides to go on the occasional hunger strike I can seem to correct that easily with some live clam from Publix at .59 a piece. Over all I have wanted one of these guys for years and have struggled, I loved having my clam too but if I have to choose one I’ll take the CBB. They are rewarding and graceful additions to the hobby. I keep my guy in a tank with a gem and Naso as well as a few smaller fish like cardinals
