I have a Coral Beauty that is kind of an anus. Bullies some of the smaller fish, nothing terrible, but definitely shows aggression to my juvi Heni and Royal Gramma. I have a 125g aquarium with enough LR to have their spots. I wanted to add Flagfin Angel, but I am a bit nervous about that CB killing it. I previously had Red Strip and Flame, they were fine, with some aggression when they ran into each other, but I am not a fan of unnecessary stress in the tank.
