standard fluorescents (aka NO fluorescents) are ok short-term i guess, it also matters how many tubes there are. But anyway you recieved a dying one from them so i wouldnt trust there lighting system. As for the dying one, if you are certain its dead remove it as a rotting coral can cause havoc on your bio-load.
i didnt get the xenias from him, i got them from an aquatics mail order, off the net.
dont worry ill never get live stock posted again.
just a silly moment of mine
