Yeah, I think the amount or rockwork/hiding places makes a pretty significant difference. Ray, if I remember right from pictures, you've got a ton of open swimming room with not much liverock in the display... We've had a Blue Jaw and a Niger together in our 160 show tank at the store; there's a ton of rock in there, and they get along fine...
Definately fish have their own quirks and personalities, so you never know till you try it out...
