how often to feed live?

Are you looking to only feed them live food or are you looking to do a mixture? It is recommended to feed your fish in a saltwater tank at least twice a day, but I feel if you may be doing a mix of live and processed it may be wise to lessen how much you feed them per day. Without knowing what you are going to be feeding them and if it's going to be a mix or not it really is difficult to give you an accurate answer as to how much and how often.
