Mutton snapper (like the beautiful one pictured above caught by Capt. Eric) love to hang out underneath schools of kingfish. The kingfish are sloppy feeders and their leftover scraps are readily picked up by mutton, yellowtail, and mangrove snappers. You may not want to catch the kingfish, but finding them will often find you some snapper!
