Johnny Darter
Etheostoma nigrum
Key differences: The Johnny Darter typically has distinct W- or M-shaped markings that are more separated and less tessellated than those of the Tessellated Darter. It also often has a more prominent dark spot at the base of the caudal fin. The Tessellated Darter generally has a more pointed snout.
Swamp Darter
Etheostoma fusiforme
Key differences: The Swamp Darter is generally smaller and has a more compressed body. Its markings are often more blotchy or irregular, lacking the distinct W/X pattern of E. olmstedi. It also typically inhabits slower-moving, often vegetated waters.
