Finescale Dace
Chrosomus neogaeus
A shimmering bronze inhabitant of North America's quietest waters, the Finescale Dace is a master of the bog. This resilient minnow brings a splash of hidden color to tea-colored ponds and northern wetlands.
Quick Identification
Size
2.4 to 4.3 inches (6 to 11 cm) in length; typically weighs less than 0.5 ounces (14 grams).
Colors
Olive to dark bronze back with a creamy white or silvery belly; features two dark horizontal stripes along the sides; breeding males develop brilliant red or orange coloration on their lower flanks.
Key Features
- Blunt snout with a relatively large mouth for a minnow
- Two dark lateral bands, with the lower band being more prominent
- Very small, fine scales that give the skin a smooth, bronzed appearance
- Deep, stocky body shape compared to other dace species

Geographic range
Where Does the Finescale Dace Live?
The Finescale Dace is native to the vast northern landscapes of North America, stretching across most of Canada from the Yukon to the Atlantic coast. Within the United States, its core range is centered in the glaciated regions of Minnesota and the Great Lakes, with significant but more fragmented populations found in the Adirondacks of New York and the upland wetlands of Maine, New Hampshire, and Vermont. It is often considered a glacial relict in its southernmost reaches, surviving in cold-water pockets left behind by retreating ice sheets.

Behavior
The Finescale Dace is a social, schooling species that thrives in the slow-moving, often acidic waters of northern bogs and beaver ponds. They are remarkably hardy, capable of surviving in low-oxygen environments that would be fatal to many other fish species. In their natural habitat, they are often found in mixed schools alongside the Northern Redbelly Dace, with whom they frequently hybridize.
These fish are diurnal and relatively active, spending much of their day foraging among submerged logs, roots, and aquatic vegetation. While they are naturally cautious to avoid predators like kingfishers and larger predatory fish, they can be quite curious when a new object—like an underwater camera—is introduced to their environment. During the spring spawning season, their behavior becomes more territorial and energetic as males compete for the attention of females over silty or debris-strewn bottoms.

Camera Tips
To capture the Finescale Dace, you will need an underwater camera setup, such as a waterproof action camera or a submersible trail camera rig. Because these fish live in 'blackwater' or tannic environments where visibility is low, placement is everything. Aim to submerge your camera in shallow water (6-18 inches deep) near submerged structures like fallen branches or the edges of lily pad fields where dace tend to congregate for protection.
Lighting is your biggest challenge in boggy water. Position the lens to take advantage of natural light filtering through the surface, or use a camera with a high dynamic range to handle the high-contrast environment. If your camera has a macro mode or a close focal point, use it; these fish are small, and getting them within 12 inches of the lens will provide the best detail of their fine scales and lateral stripes.
For the best results, use a 'stationary bait' strategy. Secure a small mesh bag filled with fish flakes or crushed freeze-dried tubifex worms just out of the camera's frame. This will create a scent trail that encourages a school of dace to linger in front of the lens. Spring is the most rewarding time for filming, as you can capture the intense reds of the breeding males. Ensure your camera is securely weighted or tethered to a stake, as even slow-moving water or curious turtles can shift your framing over time.
