I added 6 azure about two months ago. Totally fine so far. I have some big mean well-established triggers along with angels and tangs that might keep them in constant retreat mode. They spend all of their time darting in and out of the rocks. I like them so far. Nice movement in the tank.I have 5 Azure Damsels. They don't bother any other fish, look good, and have been know to eat pests off of corals.
All other damsel experiences have not been good for other fish being introduced
