the zoes i bought at the expo have not opened up yet but the star poylops have what can be the matter are they croke city or just stubborn

Some zoas are pickier than others. May be not enough/too much flow or light. May want to move them around see if that helps.

Sometimes it can take up to a week before zoa's open, as long as they aren't  looking like they have some sort of infection, you may just want to give them a  few more days
