I have a pair of azure damsels (had them since 2006). They've lived with a royal gramma for the entire time and with a tailspot blenny for several years in a 65gal reef tank without any notable aggression issues.
I initially started with a trio azure damsels but there was much aggression between two of the three so the third was relocated into a different tank. This was the only serious aggression issue I've seen among them. If I didn't relocate the 3rd azure the aggressor would have killed it for sure. The remaining pair have done very very well together over the years.
Early on I also had a very tiny neon velvet damsel (about the size of a U.S. nickel) in the same tank. The azure's did harass this fish a bit but that stopped immediately when the neon velvet equalled them in size (this damsel now resides in another tank and is several times the size of an azure and much more aggressive than the azure's have ever been).
The azure's have proven to be the least aggressive damsel species of the damsels I've kept (blue devils, neon velvet, two-stripe); the two stripe damsel (Dascyllus reticulatus)
was the most aggressive damsel species I've ever kept.
