Apistogramma can get hyper aggressive when breeding... even having the females kill the males. Rams can also get hyper aggressive, though they ussually co-parent. You would have to be cautious.
So with GBRs you could possibly do GBR and Apistogramma Caucatoides. With Bolivians there are many options with my favorite being Apistogramma Borelli (which has an insane temperature curve, in a year or so I plan on putting some in a pond).
Also, my GBRs in a community tank always eat their eggs. They freak out someone will eat their fry so eat them to keep the resources. They are at 80 Degrees F.
