New goniopora going down quickly

I acclimated this goniopora on Monday, it was looking better wed but now not so much, should I be worried? Water params are pristine, and tank mates are yellow tang, foxface 2 damsels 2 firefish, all supposedly reef safe and have never nipped at any corals. I do have a pencil urchin could he irritate it?

It's at about half way up in the tank, under 4 54watt t5 2 actinic plus and 2 white

its feeding when its puffed. i thought what in the world is wrong with that when i first seen that on mine.so did some research and learned its feeding. i noticed when my skimmer was out of order for a week the goniopora was puffed almost all the time. i now turn my skimmer off for an hour after feeding the tank.
for some reason only one of my goniopora's does this????

 

well thats good to know.

My lights have been on for about 3 hours now and its not opening though now.
