Fantail Darter
Etheostoma flabellare
Fantail Darter is a small North American freshwater darter that lives on clean, flowing streams and rivers with gravel, rubble, or cobble bottoms. Males develop a fan-shaped tail and guard eggs under rocks.

Identification points
- Adult males have a distinctly fan-shaped caudal fin, especially in breeding season.
- Body is slender and mottled brown with a series of dark saddles/blotches along the back and sides.
- Two separate dorsal fins are present, typical of darters, with a small, bottom-hugging profile.
Habitat
Clear, cool to warm streams and small rivers with moderate current; typically on gravel, cobble, or rubble runs and riffles, often near rocky substrate and under flat stones.
Bait notes
Usually not targeted as a sport fish, but can be taken incidentally on tiny pieces of worm, small insect larvae, or micro jigs. For observation or collection where legal, use very small natural offerings and minimal tackle.
Behavior
A bottom-dwelling insectivore that picks aquatic insect larvae and small invertebrates from the substrate. It is most active on or near the streambed and males may defend nest sites under rocks during spawning.
Caution
Freshwater species with no notable human consumption issue, but many populations are best released and may be subject to local regulations. Avoid disturbing spawning males guarding eggs under rocks.
Fishing notes
If fishing for larger stream species in darter habitat, fish light rigs close to the bottom with small baits and slow drifts through riffles and runs. Handle carefully and return quickly; they are small, delicate fish.
