Damsels are little devil fish...that quickly turn into bigger devil fish...
I keep reading this and hearing people say this. Mostly, yes, it is true. If you follow a few simple steps it can be avoided though.
1. Make Make the Damsel the LAST fish added to the tank.
2. Make sure it is the smallest fish, even when fully grown, in the tank.
3. Make sure it is well fed.
4. Don't put any fish in the tank that might argue with a Damsel. Hard to do when every living this has its own personality, but it can be done.
Sure, I'm new to this hobby, and most everyone has a ton more experience than I, but I learn quickly and like to find people who are experts on whatever subject I am learning about at the time. I'm lucky, I live near a LARGE Aquarium. People around me work or have worked there. Many are Marine biologists or Zoologists ore Paleontologist. I'm not afraid to ask questions.
Since Damsels are such beautiful fish, its a shame they have such a bad reputation and honestly, can be such bad fish. I added one to my tank. It is one of the sweetest fish in my tank next to my Snowflake. He is my 9th and last fish and I followed those "rules" when I added him. Those are rules I put together after asking the folks around me questions on fish behavior, pecking order, compatibility and about Damsels specifically.
The ONLY rule I broke was the size rule as he will eventually outgrow my Chromis. Of course I keep hearing that Chromis tend to be Highlander fish and have yet to see any such behaviour in mine. I know all is still new, but I'm going with the advise of local experts in the field.
Good luck with your new tank and sorry for hijacking the thread.
