tourch coral not ok?

I moved house about 6-7 weeks ago and it went very well & i did take the coral out off the water to put it in a buket when i moved but i dont think thats the problem as it was fine till last week.
The 1st head to close is still totally shut the second one made a bit off effort today to open back up but is still looking bad & the last head it perfect! I think it could have been the water!!!!!!! its was the 1st time i ever dumped water that end off my tank & it had to be stone cold!
So what now should i just leave it in my tank & see what happens? if thw 2 heads are dead or dying will they pollute my tanks? should i get it out?

Thanks :-/ K

 

Also i noticed my tanks is hot like temp 29 i run 2 heaters to i took one out & left 1 in but i think the one i left in might be playing up at its set on 25 but my tanks says now its 27-28. im trying slowly to lower the temp as i now hpw bad it can be if you do it to quick!
