Thought the name might get some more looks....

I've had this chalice for about 6 months now, when I got it it was a nice metalice blue with red mouths.

But over time it has fade to this,
(The white areas are mouths not the skeleton, iphone camera cant pick up the colors right)

the strange thing is it has been growing and a few new mouths popped up.

I have tried moving it everywhere in my tank,when I frist bought the thing I had it in moderate light but then it started fading, did some research and read they like low light so I moved it down lower in the tank. The fading didnt stop. I then was told that they like higher light but you have to acclimate them slowly, so I did that. Still down-town-brown. Now Im pretty sure I have it in too high of light, because its right by my Sps. Im thinking of trying a shady area of the tank next but rather than terrorize the chalice anymore due to fact that I know next to nothing about them I was hoping maybe some of you "chalice mad-scientist" can give me some advice?
