Other more main issues with keeping CBBF than reef safe. IMO they should only be kept in a large reef with a refugium because they are as many other BF, very delicate and not hardy to begin with, and feeding them is very tricky and most depend on feeding from esablished LR that has the type of micro and macro funa on and in it ( not generally found in a FO or even a FOWLR ) that they need untill they can, if they do, begin to eat introduced foods.
