Here's how I caught my Lemonpeel and Black Leopard.
An Ocean Spray bottle has a large opening. Cut the bottle in half and add food to bottom half. Put the top upside down but tilted to leave an opening for the fish to swim through.
The fish will swims through, knocks the top and the top closes shut.
You can see the Leopard inside the trap, nice and safe but unable to escape.
