Yes, a couple actually
First one: Turn off all the light to your tank, and for the room it is in. Wait 30-60 mins. Then, turn all lights on suddenly and go catch the fish. The fish should become somewhat disorientated, and catching him should be fairly easy.
Second one: Buy a fish trap. Problem is, you are likely to catch everything else in the tank before him (murphys law in a way).
I have a few more if you are interested, though most people would be scared to use them.
