Papaya/Green Clove Polyp are sick :(

[swampy]

The first illness has hit my tank. My Papaya/Green Clove Polyps are looking sad, they are staying mostly closed up and are turning white on their tips. All other corals look fine. My xenia had grown close to it and was bumping into it, I just separated them. Could this have caused it are is she sick.

I've had them for little over a months and they have been doing great up until 2 days ago.

My parameters:

Salinity 1.022
Nitrite 0
Nitrate 0
Ammonia 0
PH 8.4
Temp 81
note: I'm using NSW

Has any one seen this before. Thanks a bunch.

Xiena can put off toxins that harm other corals.

likely normal,they can close for a week or more for no apparent reason.
It could have been the xenia or many other thing,i have found them to be very sensitive but they normally open back up

Agreed, small upsets can cause them to close for a few days at a time. Nothing in your photo looks alarming to me...
