Natural history
FishBase places their distribution from the Yellow River system in Alabama and Florida westward to the Amite system in Mississippi and Louisiana. Adults occur over sand or silt and often remain near vegetation in creeks and small rivers.
This setting provides a more specific picture than the simple label freshwater fish: the account emphasizes quiet parts of flowing-water systems rather than exposed rocky riffles. FishTraits records bottom feeding and a mixed set of food categories, including algae, detritus, and small animal prey. Those categories indicate feeding breadth without defining identical diets at every site.
