Lol, I started out with a tank just like the one your avvie is in (I still use it as a hospital tank), I'm sure with a bit of time, willingness to learn, (and a willingness to spend money) you'll get to something like this. Unfortunately, the girls have come down with something. Three of the four have passed on :( . However, I'll be rebuilding the sorority once everything has been fixed.
The reason why it worked out so well without any bullying issues is because I had a lot of hiding spots and plants to break up the line of sight. I did my research, and the fish also were a part of it. Some girls never do get along. My girls were already in a sorority, so they had everything worked out nicely when they came to me. I also was careful to introduce the meekest first then work my way from there to finally the most agressive.
