AFAIK, Damsils are considered "starter fish" because you can add them to
a new aquarium w/ live rock to provide ammonia load and get the system
cycled and running. They are cheap and hardy enough to survive this
environment.

Problem is that they are fairly docile when immature, but grow
increasingly aggressive as they age and can only be kept with other
aggressive species. This blue fin damsel will actually turn black over
time.

As for the offending damsil, I've been planning on a second tank with
more aggressive fish (no corals or anemone), so he'll be my first if he
survives long enough.
