Well you can always reach in and grab him. Be careful not to get stuck though. My lfs guy always grabs plecos with his barehands. He is like 70 and way more hardcore than myself lol. I tried to grab a common pleco and got cuts all over my hands. I took the fish to him and he reached into the buclet and grabbed it no problems. Bushynose arent spiky like commons but they do have some nasty spikes that come from their gill area.
If you have a hollow piece of wood or tubing in general would probably work, they love caves and will hang there all the time when they find out where it is, especially when you try to catch them. simply pick the tube up, capping both ends with your hands if neccessary. I had a bn that always hung in a hollow stump. Even when I took the wood out of water he would stay wedged in the wood for quite a while because they can breath air, so if he dont come out right away give him a minute, just keep the tube over a bucket of water.
