Distinguished from other sunfish by 6 anal fin spines and 12 dorsal fin spines.


Prefers streams and lakes with clear, well-oxygenated, hard water, and boulder and sand bottoms.
Generally found under cover of rocks, ledges, logs, or overhanging branches.
Shares the same environment with Smallmouth Bass, and their food habits are quite similar, except smallmouth are far more piscivorous.


Minnows and other small fish; aquatic and terrestrial insects, crayfish, mollusks, and other invertebrates. Extremely opportunistic.
Young consume zooplankton as primary forage, adding aquatic insects and small fish as they grow larger.
Moves and feeds most actively at twilight, or at all hours on overcast days.


True to name, often caught in streams close to the rocks near the current.
Seldom achieves remarkable size and usually caught when fishing for other species.
Considered a pest by most fisherpersons for damaging baits intended for more desirable species.


Spawns in spring, when the water temperature ranges from the high 60ºs into the 70ºs. Spawning coincides with that of smallmouth bass.
Male fans out a nest in coarse sand or gravel and guards the eggs and fry.
Females contain an average of 5,000 eggs, but one or several fish may deposit part or all of their eggs in a single nest.
After hatching, the young fish are found only in quiet water areas protected from waves and strong current. Grow 1½"-2" first year, reaching 5"-7" after 3 years.


A sedentary and secretive fish spending much of its time passively hiding in the shadows of underwater structures.
