I grew a Blue face juvy into an adult and kept him with Frogspawn, Xenia, Mushrooms, GSP, Slimmer and Montipora with no problems. I tried and could not keep Candy Cane, Brains, and Zoo's. Blueface are very aggressive just like most large Angels. Felipe had a Moorish Idol at one time in his store. But like Ray stated I do not know anyone that has one?
