Morphology | Morphometrics
soft rays: 8 - 12;
Vertebrae: 35 - 37. Body very deep, averaging slightly less deep than N. merlini. Nuptial males with broad, lateral, bluish gray band; anterior rays of dorsal fin extend beyond posterior rays when depressed; when fresh; interadial membranes of dorsal fin almost entirely darkened with black pigment except for the orange along the base of the fin and bright yellow green on distal tips of anterior rays; caudal fins bright orange; anal fin membranes darkened with melanophores and overlaying wash of dull orange (Ref. 40813).
North America: middle Chattahoochee River drainage in Georgia and Alabama, USA.
Inhabits clay, sand and bedrock pools of headwaters, creeks and small rivers. Often found among vegetation and debris.

Estimates of some properties based on models
Phylogenetic diversity index (Ref. 82805
= 0.5020 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00794 (0.00379 - 0.01665), b=3.13 (2.96 - 3.30), based on LWR estimates for this Subfamily-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 3.0 ±0.2 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
