Range and Identity
Etheostoma striatulum is recorded from the Duck River system in central Tennessee. The drainage reference matters because a state-level description alone could imply a much wider distribution. Neighboring Tennessee river systems should not be added without their own identified records.
Habitat and Behavior
The fish occupies rocky pools in headwaters and creeks. These pool habitats differ from the fast exposed riffles used by some other darters. The actual bottom and channel position are useful details to retain when documenting a collection.
Food and Life History
The maximum reference is 5.6 centimeters total length, while 3.9 centimeters is common in the compilation. Midge larvae and microcrustaceans are recorded foods. Eggs occur in clusters on the underside of stones, with males providing protection.
Field Note
A photograph of a darter does not establish that eggs beneath a nearby stone belong to it. Keep adult identification and a directly observed nesting association together when reporting reproduction.
