I have a blue fin damsil nearing maturity and it's beating up my
dragonnet badly and my coral beauty showed up with wounds as well
(although I'm not sure what happened to it).

I pulled out the dragonnet, but the damsil is hard to catch. I tried
floating some food with the net ready, but damsil is quicker then the hand.

I see that there are fish traps. Do they work? Any other ideas?
