Another reason not to use Damsels for cycling.
I did try something different when I used the dividers. I tied a piece of white thread onto a #20 hook and jigged it in the tank, like a shrimp to attract him away from the
LR, so I could move the dividers. He tried to eat the fly, but w/o a barb on the hook no biggie. eventually cornered him and scooped him up.
I've used fishing equip to get jewelry out of drains, get a parrot out of a tree, get a hamster out from under a cabinet (this one was the most fun), and a few others that are just too weird for the public ears.
Good Luck
