Great damselfish choices, and great work getting these aquacultured!
I've had a trio of azures in a 65gallon tank for nearly a year, they've spawned a couple of times, but the eggs have generally wound up as snacks for my coral beauty angel. With three of them in the tank, they keep most of their fighting among themselves, though they can be aggressive with new fish. (Not all by any means - but occasionally they'll take a real dislike to a newbie, and just be relentless!) Have a pair (OK ... two) of Talbot's in QT now, and will eventually move the lot into a 220.
