Seriatopora Caliendrum "Birdsnest"

[recoiljpr]

All,

I purchased a frag of birdsnest coral last weened on Saturday. When I first purchased it you could clearly see in between the polyps and the polyps were small and kind of stringy (see the first picture). It also looked fairly "stony" When looking on the internet, most pictures I find of Ser. Cali. look like my first picture.

After a week in my tank, during the day it now puffs out where the polyps greatly expand, extend and sway in the current. Instead of looking stony, it now looks very velvety and the polyps have expanded greatly.

Is this a good thing, or is this a sick coral? I do know the second picture is bad quality. I will be getting my normal camera back tonight and I will take another shot if you need it. Take my word that the colors of the coral are the same.

My params are -
Sal - 1.024
Ammon - 0
Nitrites - 0
Nitrates - 10
PH - 8.2
Alk - 9 DKH
Calcium - 460
I use RO/DI water
