I had them both in a 92 corner before w a potters too, w out any issues, just make sure to add them together & roughly the same size. If not, in my experience, the bigger one would relentlessly chase the smaller one. And I think 3 angels of similar sizes are better than two, to divert constant harassment.
That being said, I didn't have issues w them picking on corals either. Although, w other dwarf angels I've owned; lobos, acans, open brains & other fleshy LPS were too much to resist, so careful w your acans. They usually cost more than most dwarf angels.
