A warning to those ever considering Heteractis magnifica

[Ruth]

It's funny we don't hear of this more Tony. I am sure you were super careful and fast but given your results I agree that the beast is letting off some kind of toxic chemical. I know that I have seen it in my tank with my huge green carpet and any other anemone that I have tried to add even way on the other side of a 230g. Strangely enough I have one that survived (a small GBTA) that is actually quite close to the carpet so go figure????
On another note if you do decide to get rid of that beautiful guy I would buy it from you in a hearbeat.
