oh he!! ya. I have killed three (four now) Moorish Idols and four or five CBB. I am still tempted to try another one, but I know what they need and I just don't have the kind of tankmates that will allow it to live. They seem to need shy tankmates that will not compete for food and be fed several times a day.
BTW, sorry for your loss. Even when we know it will happen, it still sucks pissing away money like that.
