I doubt very seriously that the problem was chemical warfare. The new anemone may have had an infection that affected the resident haddoni. It has been well documented that two haddoni's can live together, even touch each other, without harm.
I should try it again, someday soon. I've always wanted to keep a blue, green, red, and purple one together in a same tank, side by side, i think that would just be incredible looking. I'll make that my goal.
My tank was only 72 gallons at the time, once I removed the new anemone, and did a good water change, my original one slowly came back to life. I suppose it could be infectious in nature I guess. they were on opposite sides of the tank, never touched.
I wonder if corals over time in captivity develope different toxins in the nematocytes. example.
I had a red goniopora for over 2 years, it was huge, and would constantly brush up against my acans, and everything was fine..
one time i introduced a new one, smaller piece, and plced it near by, once it opened fully, the tenticles that touched a piece of acan burned all of the acan polyps over night.
also people say that elegance corals have very stron sting, however, I've seen them touching lobophyllias, next to each other with no issues at all.
also, sometimes my carpet will travel across my tank, crossing over all of my acans and micros, but will not do any damage to them., which i'm surprised, since he is one sticky carpet, always accidently almost taking my hand in its mouth.
thanks for all the replies.
