Zoas dying please help

[fasterznu]

So my roomates zoas all of a sudden started to close up after a couple weeks of having them. One of the colonies has died and now his fruit loops aren't looking to good, they've been opening halfway for the past week. Posting some pics if anyone can help. Thanks
