Is there anything in particular that promotes zoanthid growth?

I have a bunch of different kinds of zoas in my tanks. They all seem healthy, open up every morning and close every night. Have had them for several months but none of them seem to be spreading. I put in some Reef Complete twice a week. Is there anything else I can do to get these to start to spread some? The two star polyps I have spread at a decent clip.
