currently in my 120 i have radiant, yellow coris, six line, and in QT a velvet wrasse. My wrasse are all classified as "reef safe" and stay 5 inches or less. Are peacefull with others of the same species. Every now and then the six line gets a bit pushy but its rare, and never continues long enough to cause any due harm to the others.
I still think that you will be fine, but it would be nice to know the size of the tank.
