So I joined in a "Don't Break the Chain" trade on another site and got two VERY SMALL frags shipped to me. I think both are dead, but one might have a chance. Can Zoas lose their heads but still have healthy stalks and grow back? The reason I ask is because it looks like the stalks are alive, but I can see in them and there is nothing down there! What gives? I tried to take a pic but they are too small.
