Sorry for your loss, I just saw what happened after I replied. My angels seemed to waste away in a matter of a couple of hours too. I was told it is a species specific bacteria that only effects large species angels. Maybe this might be so with the CBB as well. If so, if you can get the fish out ASAP and treat it with anti biotic, they will come through. I was told sometimes you need to treat the 2-3 times until the build an immunity to the bacteria on their own. I thought the same thing about what you think is killing your CBBs... but my hunting and research has turned me to see it was more then likely a bacterial infection that killed my fish.

I'm not saying this might be so in your case, but it might be worth looking into a little more.
