introducing other pets

HI, can anyone tell me about introducing bearded dragons with my beloved staff, i have been told good things and bad, but dont know what to do. My son wants me to get a vivarium with a couple of dragons and have been told they will get on well. Although my Trigger is my main concern, i would like them to get on and am willing to do this, BUT, i am a big animal lover and wouldnt want any harm to come to either !!!! HELP, what do i do or what can i expect ????????

Would the bearded dragons not just live in a tank? I dont mean to sound thick but I wouldn't have thought there would be a need to really mix them, I can't imagine it would turn out very well?

Well I have snakes, lizards, hamsters, guinea pigs, hedgehogs and they have all sat with Harvey and he has never so much as battered an eyelid chance can't be with them his prey drive is far to high
