Notropis atherinoides (Emerald Shiner)

Notropis atherinoides, or emerald shiner, is a species of shiners (and true minnows) that grow up to about 3.5 inches in length and live to a max of 4 years. They are native to North America from Canada to the Gulf of Mexico, and are a common minnow and are also a popular bait fish, along with the golden shiner. Emerald shiners are known to school, which a school is usually circle-shaped or oval-shaped from above (if there is not enough room then they may make more of a cubic shape).
