it depends on what you want.community,breeding,solo fish? you could get female JD,try to breed them.you could add a school of SD,or bigger barbs.or add 2 cichlids:nics,freddies,bocourti.salvini,syns.many options but you may have to get a few see how they grow out for a while as a group.sometimes as the fish hit adulthood,things possibly get rough.
