Hows the footSuccess! Many thanks to @fishguy242 for the idea. I twisted 2 strands of plastic coated wire together for stiffness and shaped a hook on it. With the endoscope pointed at the nem, my wife holding my phone so I could see the camera view, standing on a chair to get above the tank and a struggle to get the right angle, and maneuver him around the spacers separating the glass and acrylic, I managed to bring him up!
He is now rehabilitating in a 20g observation tank I luckily had running.
