LPS ID Plz!

[eefan]

I got this frag last weekend at the Michigan Coral Swap and Expo from Pacific East Aquaculture. I asked them what kind of coral it was and what its requirements were. They said it was a Cyphastrea and it needed mod light/flow. To me, it doesn't look like any of the examples of Cyphastrea I've seen online. I had it in a spot in my tank where I thought it would happy, but it's lost a lot of it's color. When I got it, the base was a deep purple with bright green polyps. Now it's more brownish with neon yellow polyps. I'd hate to have it die out on me. If anyone could help with care requirements or, at the very least, an ID, it would be greatly appreciated. Thanks.

Looks more like a Favia to me, but hard to tell from the picture.
