Is my Xenia and Tree Coral to close together? (pic)

[fishforlife]

Is the Xenia and Tree Coral to close together? They both have grown and the tree coral fragged. Rarely does the Xenia's "hand" close even when the current brushes them together.

Thoughts?

If one or the other begins shriveling, curling up or showing lighter/darker tips, I would move them. They may be fine if they are use to being next to each other, neither feels threatened.

My tank is overgrown with both. They grow all mixed together, sometimes growing onto the stalks of the other.
