Bullhead Minnow vs Pugnose Minnow
The bullhead minnow and pugnose minnow are both small, unassuming minnows sharing similar wetland and stream habitat across parts of the United States, yet their mouths point them toward opposite ends of the water column.

Bullhead Minnow vs Pugnose Minnow: common questions
How do the bullhead minnow and pugnose minnow feed differently?
The bullhead minnow forages along the bottom and tolerates murky, silty water better than many other minnows, while the pugnose minnow has a small, sharply upturned mouth built for picking food from just below the water's surface and among floating vegetation, a completely different feeding zone within the water column.
Why is the pugnose minnow called that?
This species has an unusually small mouth angled sharply upward, a feature reminiscent of a pug's flattened, upturned snout, which gives the species its common name and reflects its surface-oriented feeding habit, quite different from the more typical forward-facing mouth of the bottom-feeding bullhead minnow.
Which minnow tolerates murkier water, the bullhead minnow or the pugnose minnow?
The bullhead minnow is the more tolerant of murky, silty conditions, allowing it to persist in streams and reservoirs degraded by sedimentation, while the pugnose minnow favours still water with better clarity and abundant aquatic vegetation, making it somewhat more habitat-particular than the bullhead minnow.
