No you don't have to feed every mouth. Just feed the coral as a whole. It will guide the chow to whatever mouth is closest. I have three opens,. I just drop silversides on it, it picks the mouth. All are doing very well and growing. Do you supp. phyto as well? The only corals I am aware you have to feed every mouth is the branching kind. Each branch is an individual animal, where a brain is one.
