How to catch a damn damsel out of your reef!

This my story on how I was able to easily catch Damsels out of my reef. I noticed that the 3 damsels in my reef were terrorizing the other fish; even harrassing my yellow tang so much that it was so stressed out and decided to take a permanent dirt nap! ARG! Anyhow, after unsuccessfully trying to net them out, I decided to get them when they least expected it - in the middle of the night! I waited until about 3am when the lights have been off for a few hours and turned all the lights on. After the lights were on, they just floated around and I just netted them out. Yep, it was that easy! I'm not sure if that will work for everyone but it worked great for me.
