Range and Identity
The retained name Erimonax monachus corresponds to Cyprinella monacha in the checked source. Historical accounts include several Tennessee tributaries, but named localities should remain dated rather than being treated as a complete current population map.
Habitat and Behavior
Young fish associate with smaller gravel and moderate current, while adults occur around boulders in faster water. Both stages use clean river riffles and runs. A juvenile survey can therefore sample a different part of the river from an adult survey.
Food and Life History
The upper reference is eleven centimeters total length, with seven centimeters as a common size. Aquatic insect larvae provide food, especially midges, blackflies and caddisflies. Eggs are deposited in crevices among boulders, linking reproduction to coarse river structure.
Field Note
Retain life stage and both scientific-name forms when comparing records. This keeps older observations searchable while preserving the contrast between juvenile gravel habitat and adult boulder-associated current.
