I think in the Damsel world, temperment has to do more with size than type. I had a domino, three striped, and blue tailed and from what I found whichever is the biggest is the meanest. My domino was the largest and beat the crap out of the other two. SO i thought it was the fish itself, so i returned it to the fish store. Well a few weeks later the three striped started beating up on the blue tailed - because it was now the biggest fish.
All Damsels are pretty territorial, when they are juveniles and small they tend to not be as aggressive, but the larger/older they get the more mean.
This is just my experience with Damsels - i still have my three striped and blue tail.
