Well thanks everyone for the suggestions. I was able to get the little guy out. I did try flooding the over flow, and turning off the return pump. It seemed like he didnt want to get out. Most of the time he swims low to mid level in the tank. It was tough to get to him because of the pipes, plus the over flow box is pretty tight as it is. I ended up draining the overflow, with the return off. Then cornering him with the net, and using my stick to put him in the net. I was more worried that he would be stressed, but everything is ok.
