Hammer Coral Issue

[reefnano111]

Hi guys,
Could you please help indentify what is wrong with my hammer coral ?
I have another 2 euphillia beside him but they seem to be fine. The last picture is when I got him home 2 months ago but since I upgrade the light and move the rock it just doesnt open as big as it used to be. The 1 first 2 pictures are the current stage, is it bleaching or dying?
Salinity: 1.026

Since you upgraded the lights and moved it, it needs time to adjust. How long has it been at the new location? Does your new light have an acclimation mode?

I didnt know that I need to acclimate them at the time but it is on acclimation mode now and I turn down the light intensity.
It been at this location for a month now. I recently moved it again due to my fish like to stay in that area and it got disturbed once in awhile. Also the tentical loose it green tip and way thinner when the light is on. The last picture took this morning when the light off.

As Tuan suggested, just give it some time to adjust - especially if you've moved it twice in a couple weeks. Also looks like a very new tank, so let things settle. Sometimes the hardest thing to do, is to do nothing - when that is what is needed : )

Thank you for your help.
I will leave it alone. Yes the tank is about 2-3 months old.
could you also identify if the red thing on my rock is caroline or some sort of bad algea ?
