Central Mudminnow
Umbra limi
The central mudminnow is a small, slender freshwater fish that lives in cool to warm, quiet waters with soft bottoms and dense cover. It is a secretive species that often hides in vegetation or debris and is more commonly encountered than targeted by anglers.

Identification points
- Small, elongate minnow with a blunt head and small mouth
- Dark mottling/banding along the sides, often with a dusky overall brown-olive tone
- Rounded tail and short dorsal/anal fins set far back on the body
Habitat
Shallow, slow-moving or still freshwater habitats such as marshes, backwaters, ditches, ponds, and vegetated edges over mud, silt, or detritus; commonly associated with dense submerged vegetation and low-oxygen waters.
Bait notes
Rarely a deliberate target. Small live worms, bloodworms, tiny insect larvae, and very small jigs or micro soft plastics may take them incidentally; they also strike tiny baitfish-like offerings when present.
Behavior
Benthic and cover-oriented, often remaining hidden in plants or bottom debris and feeding on small aquatic invertebrates and zooplankton. It is generally not a pursuit predator and is active around cover rather than open water.
Caution
No major species-specific consumption hazard is well established; local water-quality advisories may matter more than the fish itself. Follow local regulations and avoid keeping fish from contaminated wetlands or ditch systems.
Fishing notes
Fish very small bait under a light float or near dense weeds, using subtle presentations and minimal weight. They are often caught by accident while fishing for panfish or minnows in shallow backwater cover.
