Morphology | Morphometrics
soft rays: 7 - 9;
Vertebrae: 30 - 32. Modally 8 anal-fin rays; 29 or more predorsal circumferential scales; absence of basicaudal spot; breast fully scaled; upper jaw large, length greater than 9.4% SL, extending under orbit; gular stripe reaching under orbit, not to isthmus; breeding males with many large tubercles over head, with narrow gap on rostrum, not organized into rows, less than 16 non-marginal tubercles on caudal-peduncle scales; both breeding males and females with distinct plum-colored lateral stripe below iridescent light-yellow stole; and scapular bar absent or weak; mouth terminal to subterminal (Ref. 42680).
Inhabits spring, most adults occur in the upper meter of the water column and near the margins of the cattails or in the growth of cattails surrounding the spring. Few individuals are found in the open water column and near the substrate; relatively few fish are seen in the shallow marginal waters. Forms schools of at least 500-600 individuals .

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00851 (0.00374 - 0.01935), b=3.06 (2.86 - 3.26), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.1 ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (12 of 100) .
