Cypress Darter (Etheostoma proeliare)

Description: 

The Cypress Darter is found in Gulf Coast drainages from Texas to Florida and north in the Mississippi Embayment to Illinois. As the common name suggests, Cypress Darters are found in slow-moving water over soft substrate and are often associated with vegetation and cypress knees. These fish have a maximum size of 2 inches, making them one of the smaller darters.
