My particular dwarf sucks. He chases everyone in my community tank except a pair of pearl gouramis- he tends to ignore them or get close to them but not give chase (the pearls ignore him, they happen to be female too). I used to have another male dwarf in there with him, but that one got incessantly bullied to sickness and was quarantined. After I started rearranging things in the tank on a weekly basis, he quit being such an aggressive dork.
I've read on more than a couple occasions that honey gouramis have a softer disposition than dwarves; in your case, you could consider having a ratio of more honeys to dwarf. I'm pretty sure that would be more successful than a 1:1 ratio.
