Corals will go through stages were they wont open at all if not only a little bit. As long as they arent coming off of what ever they are attached to its good. When they do open back up they should be bigger then before.

I have been watching mine and each one is different some will stay closed for about a week but some will stay closed a day. NOw if you start to see some stuff coming from them more then likely they are dying. Or like I stated earlier if they falling off the rock.

Rumor is they are multiplying when acting as yours are. However if their needs are not being met they could also show similar signs while wasting away. What are your lighting and current conditions?

coral not opening

i'm havint the same problem with my yellow polyps, a couple of them haven't opened for the past week, i checked my water and everything is fine and nothing seems to be growing on them or around them. however, a couple weeks ago two polyps or so did fall off the rock and reattached themselves and are doing fine now. should i be worried?
