Usually for Kingfish, its Bloodworms and clams, looks like thats a clam showing in the photo, so it would have taken the bloodworm. Kingfish rigs are 2 hooks, 2 small floats we usually bait the hooks with a different bait on each hook (gives them a choice ) and works well, we did pretty good on kingfish this year.
Side note......if your fishing with bloodworms, watch out they bite and it hurts like heck. Like a bee sting x 10
