What is "spottail shiner"

The spottail shiner or spottail minnow (Notropis hudsonius) is a small- to medium-sized freshwater minnow. It can be found as far north as the Canada and as far south as the Chattahoochee River in Georgia. These shiners live in lakes, rivers, and creeks. They occupy the rocky or sandy shorelines and bottoms of the water. One of the defining features of a spottail shiner is the black spot found at the base of the caudal fin. These shiners generally spawn from late June through July.
