Help!!! unhappy xenia and zoa's

[saltwatersucker]

I woke up this morning and my xenia didn't look particularly happy but she sometimes can get up on the wrong side of the bed so I went about my day but she never got any better and actually progessively got worse as did my zoa's but the weird thing is that all of my other tank inhabitants including my button polyps and my star polyps are doing fine. Here are pics of each of them if anyone has an opinion on why this is happening I would appreciate it.
Thanks

What other corals do you have in the aquarium? And do you know what the tank parameters are? If it has been a while since your last water change, you may want to start there.

Salt,

Your salinity and temp seem to be a bit low. See HERE (http://www.reefkeeping.com/issues/2004-05/rhf/index.php)
