Torch coral losing flesh

[whitasm]

I am hoping that someone can provide me with some insight on this issue. My torch coral is about a week old to this tank and I have noticed some of the flesh is receding. In the pictures you can see the white skeleton showing where it is receding. Tank parameters below :
Nitrate - 10
Phosphates - .25
Calcium - 455
Magnesium - 1275
Alk - 7.7

Looks ok to me. Perhaps a better picture with a flashlight on the side and no flash from the camera would help

I can try and get another picture tonight. Checked on it again this morning and it appears its moving up even more. it is that white skeleton showing in the picture as it appears just a patch on both sides of the skeleton are moving upwards. All other corals are fine and it is a tank full of Euphyllia.
