Finicky Ficus

We gladly inherited some trees from a friend that moved back to the US despite having no knowledge or experience with trees of any sort.  They warm up our house, reduce echos and generally make it a more comfortable space.  Aside from that, they are a pain. 

We are now the proud owners of two ficus trees and two palms of some sort.  The palms are a piece of cake, it's the ficus trees that are making me mental.  When we first brought the trees home, both ficus trees lost about half of their leaves.  After some internet research and moving them elsewhere in the house, we finally found a home for each tree. 

All was well until we put up the Christmas tree and had to move one of the ficus trees 20 feet from his home.  Wouldn't you know it, that tree has now resorted to weeping in the corner.  Everyday there is another pile of dead leaves waiting for me underneath the tree.  I don't know which one is worse, keeping the tree where it is and hoping to ride out the storm, or moving it again and risk the finicky fallout. 

At this rate, it's going to make Charlie Brown's Christmas tree look like a redwood.  Any thoughts on how to help our ailing ficus?  We will reunite him with his favorite spot after Christmas.
