Eliminating angelfish aggression

I tried to train mine, every time an angel(ha-devil) was gonna attack the other I would point my finger at it and say 'NO', it would stop. for about 5 seconds. But each time, I put my finger up, it would not even advance,you can always tell when it's gonna charge, a couple of times of waving my finger at it, then it would just swim in another direction instead. I bet it said to the other"I'll get you later!"
 
"Three Angelfish doesn't usually work out well. If you have a pair, you're lucky, and they'll stay friends for life. But in threes, it's not uncommon for one to be bullied by the pair, and eventually that bullied fish weakens and gets sick. Do remember angels are schooling fish when young, territorial pairs when adults."

I'm quoting this from here: http://www.wetwebmedia.com/FWSubWebindex/FWAngDisF6.htm

^QFT!
yes i fully agree with platytudes saying that angels are friedly youngs but can become bullying ones when adults near to mate and odd numbers adds to this problem when pairs mark their territories , though i am not very very experienced but had similar problems with me when they paired up and laid eggs , they eliminated all guppies buy taking them as food and cornerd the other 3rd single angel, if there is a plenty of space to hide or dotch a the frequeny and intesity of being bullied decreases very much, few things one can try that i did separate the pair by removing other single at least for sometime or separate them by a transparent separator so that they do not get physical to each other in this way they stay protecting their aggs like in nature with less or no damage at all.
i hope you did not mind my expression here. thanks
 
angels become aggressive mostly when they start to pair up before that they are very peaceful and schooling , and there is another thing that i noticed is that when you give them more live feed by hands they fight and thrive for food and your attention ,each of them tries to get all the food quickly so i used to put the estimated food all at once by spreading not by picking them one by one, though it is a pleasure to see fish taking food by hands but i think it somehow triggers a sence of compitition between them and once they start to pick up on each other it is difficult to stop them the more we try to stop the more they go for this, please ignore my little experience and poor english. thanks again.
