Don't give up on her!!! It took me 2 days for my PB. I'll never forget catching the male, putting him back and then seeing him swim back to the bed where she joined him. The male was a chunk, when she swam up and her head was at least 4x his I about passed out. The best tip I can give you is to try and make yourself not part of their environment, and don't chunk stuff right on top of her. Don't be afraid to go little, or trying a reaction strike. If you get a chance try a 5" or 6" Skinny Carrot wacky rigged - no weight. It will enter the water quietly and is very non-threatening. I had a lot of fish pick it up just to move it off the bed.
Best of luck!!!
