Sure way to tell, remove it from the tank and smell it, acros have a pungent smell if they have tissue. Dead have no smell at all.

True but very rare, for the most part if the coral is bleached and not showing any polyps it's not coming back. It's very difficult to tell whether it still has tissue or not. Perhaps I should have been more clear.

I give up up and throw it away when the coral is white and shows no polyps, that to me = dead.
