Etymology: Percina: Latin, diminutive of perch = perch (Ref. 45335); tanasi: Named after the former capital of the Cherokee Nation, which was located on the Little Tennessee River, the type locality (Ref. 10294).
Environment: milieu / climate zone / depth range / distribution range
Ecology
Freshwater; benthopelagic. Temperate; 36°N - 34°N
North America: upper Tennessee River drainage of eastern Tennessee and northern Georgia in the USA.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 9.0 cm TL male/unsexed; (Ref. 5723); max. reported age: 4 years (Ref. 12193)
Occurs in gravel and sand runs of medium-sized rivers (Ref. 5723, 10294); also found in creeks (Ref. 10294). Feeds on small pleurocerid river snails, mostly Leptoxis and Lithasia, as well as some physid snails and limpets; also consumes caddisfly larvae (Glossosoma, Hydropsyche, Brachycentrus), midge and blackfly larvae, and a few mayfly nymphs (Ref. 10294).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00537 (0.00235 - 0.01227), b=3.14 (2.94 - 3.34), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.4 ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref.
120179): Medium, minimum population doubling time 1.4 - 4.4 years (tmax=4; Fec=100-600).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
