Very nice pics and great looking tanks Japes!!  The Heckelii can definately be a little aggressive.  I have one male in my 220 and it dominates the other geo's and is pretty nippy.  I can't imagine what it would try to do to another male.
 
I really like the look of the Laetacara dorsigera in with the orangeheads. I just added a dimmerus to my gymno tank that has sort of the same effect.
 
Your tanks look really nice!!
