I have a SHOW size Blue Ring angel coming this week along with a small undulated trigger. I've always wanted an undulated so I figured i'd try it. I have a spare tank I was going to put him in, but was wondering how he'd do in my aggressive/semi-aggressive community tank that consists of many tangs, triggers and wrasses. The undulated is around 3-4". Worst case scenario I pull him and put him in a tank of his own.
