Species
Banded Darter
Etheostoma zonaleBanded darters navigate brisk, clear river riffles by darting from rock to rock, using their pectoral fins to brace against turbulent currents. During the spring spawning season, males flare intense emerald-green vertical bars and bright red markings along their dorsal fins to court females among submerged mosses and river algae. Females lay adhesive eggs directly onto strands of aquatic vegetation, relying on swift oxygenated currents to keep the brood healthy.

Responsible observation
- Viewing Gear: Use polarized sunglasses or a clear underwater viewing bucket to spot them resting in sunlit riffles.

- Water Quality: Look for them in cool, clear, mossy streams, as they vanish quickly from waters fouled by silt.
