In the future, if you ever ned to remove damsels from your tank:
Take a small bottle of water with the screw top. I used 16 oz bottle. Take cap and plastic ring off. Cut off top of bottle, invert it (so the top is inside the bottle pointing at the bottom) and staple around the top edge to kep it in place. Drop a cube of mysis in it, take the label off, and submerge. Watch the tank (preferrably do this on a feeding day before the fish are fed) and as soon as the damsel enters the trap, just lift it out. That's how I got my damsel out of my 10g reef. It was WAY easy.
