Need a little more info about your tank Mirkus before we can begin to guess like lighting, how long it's been set up, how long have you had the coral, what else is in the tank, what are the water values, etc...
I bought a small frag from a mail order company once. When it arrived it was brown like yours.. gradually it did lighten... and the polyps began turning green.
The back side of mine, the side receiving the most light under the 250w MH, was the lightest.
I'm sure this has somthing to do with lighting, although I can't put my finger on it.
I can say that although it did lighten in color it has more than tripled in size since December.
My guess is that you're fine. You may just be using a stronger light than it was grown under.
That's a lot of light, it could just be too much for it or the stress of moving or both. I've never had one of those bleach on me, but when other corals I've had did that I moved them down a bit and left them alone. Most of the time they came back.
I would guess that brown isn't its natural color and the change in lighting is causing it to adjust. Like lawdawg said, try moving it to the bottom so it can get acclimated and work your way up to its final spot over a few weeks.
They can turn different colors actually. I have one that was a light brown when I bought it but under MH lighting turned a lovely dark brown with electric green tips.
I always thought they were pink, I have a fist+ sized colony that is pink and haven't seen anything different. Please post a picture of the brown with green tips LawDog. thanks.
Mine's small, see the turbo snail in the blurry foreground...sorry my digi camera stinks, but you'll get the idea. It seems a bit thicker than most I've seen, but it is a small frag off a much larger colony so I'm hopng it gets more elongated as it grows.
you know, I'm not sure Pit :lol: . I got that when it was one branch the size of my thumbnail as a birdsnest from the LFS. When I took that pictures, I looked closer at it than I have in a while...
Actually I don't know, there is a pic of a seriatopora in the Vernon book that looks kinda like what you posted. I don't know what I'm talking about, I'll shut up.

I vote poccillipora......I have lots of that. Seritopora IMO has a different growth form. Sort of thin and dainty at the ends where poccillipora is much more rounded. I have pink and brown poccillipora in my tanks.
