Well, I was needing some help on my new additions thread, but I guess you guys decided to dodge it

What do I feed these new guys?? I have:
1 Green Star Polyp Colony (The mat kind)
1 Greencentered brown skirt zoos
1 "unknown zoo" it hasnt opened yet
1 red mushroom
1 blue mushroom with green spots
Also, my "unknown zoo" and my green star polyps arent all the way out. The "unknown zoo" has a green skirt, and I believe an orange center. The green star polyps have only 4-5 polyps out, but theres a whole rock with a nice big mat! Why arent there more out? They dont have that long of polyps either. Here are some pics
