Help GSP and Zenia Chemical Warfare

I have had these two corals for about a month (Green Star Polyp and Zenia). Recently the zenia, which just split into two separate stalks has been looking wilted. Is it possibly (or likely) that the GSP is harming it through chemical warfare? They are far apart but the flow is enough that it likely wouldn't matter if they were on opposite sides of the tank.

I have read that both corals (and mushrooms which i also have) perform this chemical warfare but there is little consensus on how to deal with it or which corals are worse. From what I read the GSP is one of the worst for chemical warfare. Should I just get rid of it? (I already run 2x the recommended level of chemi-pure). I did not know when i bought it how severe the effects can get and I dont want to see my tank fall apart. Any suggestions?

I never had a problem with my GSP. They covered an entire rock and I had a frogspawn, a toadstool, muchrooms, a red chilie coral and yellow polyps all very close (I only have a 12 gal) and I never had anything sting or chemical war each other.

Did you dip it? Are you sure you didn't pick up some kind of hitch hicker?

Do you have a pic?

 

no dip but all corals were captive grown pretty sure there is no hitchhiker. GSP looks amazing (pictures coming as soon as possible) but my mushrooms have gotten a bit smaller and my zenia looks very wilted like if i touch it it will fall apart (also will be posting zenia picture) everything was fine for a while the zenia even began to grown on the LR i placed it on then all of a sudden (last 2 days or so it has been very closed up).

 

images are attached and the corals are about 8 inches away from each other, p.s. also have a palm tree coral (culvera or something) thats been all closed up (in the zenia pic on the bottom). could it be the problem?

 

I'd be more inclined to think water parameters with the xenia, or just nothing LOL.

Our xenia struggles. Some days it looks like it's getting bigger, other days it looks like it's getting smaller and suffering. Everything else looks fine. Some people have xenia take over and others can't grow it at all. Unfortunately, no one really knows enough about xenia to ever figure why it does any of the things that it does. Supposedly it likes nitrates in the water, but obviously that's not the only key or it'd be taking over the tank by now (we got it in December)!
