Wow! I'm amazed at your patience! Great job!
I can't really comment on any other fish but the Blue/green Chromis. I found that when I had more than 1, the dominant ones would pick on the weaker ones until they finally all died. I started with 3, but ended up with one.
It could be just my fish though, who knows. Good luck!
