I use long shanked light wire hooks with a real wide bend and the barbs pinched off, i found light wire offset bass hooks work quite well. Wider bend keeps them from swallowing them to to deep, still can hook them easily since they have quite a big mouth, and the long shanks and barbless help you pop them out easier when the do swallow it, and as a last resort you can cut the hook off and push it back out or hope that it works its way out.
