Tail hook him on 6/0 or 8/0 owner mutu light circle hook and hold on. I fish 6” croakers all the time in the bay down here for the bigger specks and slot reds and you’d be surprised at how many 3 lb specks or 4-5 lb reds will eat that 6” croaker or bigger. You’d be amazed at how big a bait most saltwater fish will eat. I think a 9-10” croaker is really the perfect bait for big bulls.
