how to tell if gsp is dead?

Thanks,i'm pretty bummed too,alot of people find it a bothersome coral,but i love it and can't find it around here.I did find the heat packs jonjon put in there,but it was very cold(about 30 deg)the morning they got delievered and when i pulled the bags out of the box the water was ice cold.Jon sent a couple other frags along with the gsp(he was so great about packing them and so generous,but sadly none survived the trip.

 

if there is even any small bit of tissue left, it will grow back.

you did found out the answer, if its dead, it will completely disintegrate.
