Rainbow Darter
Etheostoma caeruleum
Rainbow Darter is a small, colorful North American darter that lives in clear, fast streams with gravel, riffles, and runs. Males show bright blue, orange, and red breeding colors; it is not a typical target species for anglers.
Identification points
- Males have vivid blue-green body markings with orange-red bands during breeding season
- Distinct dark vertical bars or saddles on the sides over a pale to olive body
- Small darter with pointed snout and two separated dorsal fins typical of darters
Habitat
Clear, cool to moderately warm headwaters and small rivers with swift current, riffles, gravel, cobble, and submerged rocks or bedrock; usually near bottom in shallow flowing water.
Bait notes
Rarely targeted; if caught at all, use tiny hooks with live mayfly larvae, worms, or small insect imitators. Micro jigs, bead-head nymphs, and very small spinners can take them incidentally.
Behavior
Benthic insectivore that picks mayfly, stonefly, caddisfly, and midge larvae from the streambed and drifts. It stays close to rocks in current and is most active in daylight, especially during spawning when males become brightly colored.
Caution
none notable
Fishing notes
Fish ultra-light gear in riffles and along current seams over clean gravel. Dead-drift tiny nymphs or drift natural bait near the bottom; keep presentations small and subtle because they strike while foraging on benthic insects.
