Zoas only opening on occasion

[Thade_hicks]

I have an EVO 13.5 MIXED REEF. I have Duncan's, Kenya's, torches, hammers and more. The only corals that I'm having any issues with are my 3 Zoa colonies. For the last few weeks they will only open on a semi rare occasion. All other corals are acting fine. They are all in different parts of the tank, and I haven't seen any nudibranches or spiders on any of them. The coral will still illuminate under the blue light slightly so I know they aren't dead, HELP!!

Assure not too much light or flow
They don’t need the requirements of sps and many coral
I’d leathers are present, they may release a toxin known as terpenes and upset the zoa
Give them gentle blasts with a turkey baster to assure no sediment or mulm is annoying them

Yes, I have a fair size leather. How can I tell if that's what is causing it?

My leather has been sliming recently also. Would the toxin effect any of my other corals?
