Flower nems killing my corals?

small alien

The fungus is among us.
Not from stinging, but has anyone ever heard of flower nems toxifying the water in some way that would kill corals. All my LPS went straight down hill (color loss and recession) after I added two small flower nems to my tank. It's the only thing I can think of. Tank is steady and I've had nothing but good luck with corals over all. Any thoughts are appreciated. Thanks, small
 
Allopathy? I have heard they can release nematocysts into the water. Can't actually site a source as I can't remember where I read this. Research is in order.
I have never had problems but I don't keep LPS, just softies. Are you running activated carbon?
 
I was beging to think that same thing!The anemones are fine and the corals look bad.What are your leves testing out at?
