There is a difference between the blue reef chromis and a blue devil damsel, although both are damsels technically.
Meowser, I have a new favorite fish that maybe you should take a look at. Check out the marbled wrasses. They will hold their own, yet aren't aggressive. Super active, very flashy, with a huge personality. I have them in three of my tanks and they are all great fish. After only a few months, they all eat from my fingers and swim around my hands when I am working in the tank (this is a bonus as when they are around, my clowns stay away, lol).
