So before I begin i'de like to make it a point that 'I DONT WANT OPINIONS FROM PEOPLE WHO DON'T KNOW WHAT THEY'RE TALKING ABOUT!!'  really that gets annoying, if you keep discus with angelfish then your obliged or if you have a big tank with similar fish (I don't know what they could be)

So I got my 125 recently set up, I have six juvi discus in there and they are doing fine (still need to do the aquascape, replace the ballast on the lights, paint-ball co2, ect) but what I would like to do in the future is introduce a breeding pair of angels into the tank (I don't expect to breed them for a while/raise their fry).  I have heard mix reviews of people keeping the two species together, some work out just fine; others end up with a dead fish!  So please, I'd like to get your experienced knowledge on whether I could do this..  (I'm not worried of the discus attacking the angels, but the opposite)
