Hammer coral dying??

[ReefKeep66]

Hello all, got a 2 head hammer coral from my LFS about 2 weeks ago. He's been seeming to do good but not as open as the other head. Here in the past couple days has been closing up more and now has some damage on it. Don't really know how to describe It so I'll include some pics. Anyways, my parameters are in check, sg 1.024, ph 8.2, etc but the only thing I can think of is temp fluctuations. Running a 150w metal halide. Through out the day and night it'll go from 77-80. But all other corals doing fine? Thanks in advance!

yep its on its way out. all i can suggest is pulling it out and blowing off the dead tissue and move it to a place with less flow.
