If a fighting fish gets snagged on any "attractor" it usually stays snagged until it breaks loose...one wrap around and the resistance is too much. Christmas trees to start, replaced with those balls into which you glue pieces of 1/2 " pvc, and added two Mossbacks also. I have pulled out almost all of them for now...they do make interesting sculptures laying around the landscape. I love the water lilies...at the peak of summer they cover about 20% of the pond...and I've never lost a fish even when caught in the middle of the lilies, to be hauled ten feet to clear.
