How To Get Live Coral Zoanthid Polyps To Open?

How did you acclimate the new coral in the new tank? because the Zoo's were in complete darkness for a long time during shipping. if the lights in your tank were on you might have shocked the coral. you have to open the container slowly, and slowly introduce the natural light (sun, lights in the room that might be on.) Tank lights should be off once sufficient time has elapsed so you can acclimate the coral properly.
