They just seem to hang out with each other. When I first put her in with him in the 55 I had he took after her but no mating. then I changed cages and put them both into probably a 90 gallon or so(its custom built and like 36 tall by 32 inches by 18 or so) I'll get a pic on sometime. But would putting them in a new cage at the same time affect the male's agression? Since he didn't have any territory established and all.
