Flounders and redfish often feed side by side, although each goes about the business of catching prey differently. More like a trophy-class largemouth bass than any red, flounders are primarily ambush feeders. Their ability to change topside coloration and shuffle themselves into the sand or mud renders these fish nearly invisible to passing baitfish or shrimp. Their chance of reaction or escape is about the same as that of a fly buzzing off the end of a frog's nose. Flounder fishing can be excellent in the few major passes along the upper Texas coast, especially during the spring and fall migrations between bay and Gulf.
Action can be just as good along bay shorelines, in the mouths of channels or over grassy flats.
Mud minnows are a favorite meal. Small mullet and shrimp finish almost even in the two slot. As artificials go, small plastic shad or shrimp imitations on lead-headed jigs work best. Gold spoons can be good at times, too, especially along bay shorelines. I have caught flounder on swimming plugs and topwaters, but both are low-percentage choices if flounder are the main objective.
