DAMSELS what is your opinion on them

[tt101]

hey guys,
i am really looking to add some colorful small fish to my tank and time and time again i gravitate to the damsel tanks.....something about that bright blue and yellow just magnetically pulls me towards them....but alas i keep hearing about their aggression so i slowly and saddly turn around and walk away from it without looking back. the other day i was at a lfs and the had a 125g display with some type of tang and a pair of clowns and a few other randoms but in it they also had a few azure and blue and gold damsels so that got me thinking. if they can live peacefully if introduced after everyone else is well acclimated?
thanks for the help
