Melting/dieing Large Green Palys

Hi There - Two of three large green palys appear to be melting/dieing.

1. Are they dieing?
2. Should I cut out the dead ones with a razor blade and leave the healthy one?
3. Just added a cleaner shrimp - any chance he got at it?
4. Any other thoughts on what could be happening here?

Update - the paly is fine, I think it might have been giving off some toxin or something. Now the problem is that the zoas next to it won't open. I thought they may not get enough light as they are kind of under an overhang. I've moved them up in my tank,away from the palys, to see if they'd open. A bit disappointing because they looked great in the store and I was hoping the palys and zoas would grow in between each other. Any idea why they aren't opening??

Zoas can take a few days to open in a new surrounding. depending on what kind of light you have over your tank, I would start everything somewhat low in the tank. Placing a coral coming from a t8 strip bulb at the lfs, directly under super strong lighting, can do more harm than good.
Try to start everything low and work them up to the places you want them over a period of days or even weeks.

Thanks mr x - I had the zoas low in my 30g tall tank for two weeks. They were open a bunch at first and now are all closed up. Since my tank is so deep I thought maybe they were too deep, plus the fact they were under an overhang I thought they may need more light. My lfs had them under professional lights with a lot of other corals.

In the wild, they can be found in much deeper water than your tank. That said, zoas don't close up because of not enough light. They will open more and stretch out, appearing taller. I would look to another factor. Perhaps flow or parameters.

Hmm-that's what I was worried about. They like moderate flow right? I'm only running a 600gph power head, but I think it should be enough flow. Parameters looked good yesterday, nitrates, trites, alkalinity, salinity were good. PH was about 7.9 a bit low. Any other parameters I should check that may be causing it? I'm starting to lean towards disease possibly, I've read a bit about dips - should I try one?

If they were doing fine for weeks and then won't open after you moved them, I would not be thinking disease.

I got them from the LFS three weeks ago, full open week one, half open week two, now closed up. Sound like a parameter issue then? Any suggestions on what else to check??
