Sounds good to me... I heard this has happened with the same shipment of corals with another member, so I was just making sure. I have had my tank running for over six months, so I know things like this can happen to me at this point. I have got a flat worm problem on my acros, but a couple of the corals that have colour changed are not acros, so I thought I would also check.
I run three 250w halides at 14000K, they used to be 10000k, but this has been happening prior to the change, and I am not sure what to think. If I did not have the flat worm issues, I would ask my buddy to put them in his frag tank to see what happens to them...
I did find an article on the dying of corals... but it is speaking of the soft versions, instead of hard corals.

My hubby did buy a sick yellow seabae anemone and it is slowly losing the neon yellow, so I know for a fact it is dyed. It is healthy just not a colour you see in this type of nem.
