Maturity: Lm ?  range ? - ? cm
Max length : 4.7 cm TL male/unsexed; (Ref. 5723); common length : 3.5 cm TL male/unsexed; (Ref. 12193); max. reported age: 3 years (Ref. 12193)
North America: Lower Roanoke River drainage, North Carolina; south to middle parts of St. Johns River, Florida; west to Brazos River drainages, Texas; and north to lower Wabash River drainage, Indiana and Illinois, USA.
Occur in swamps, heavily vegetated sloughs and small sluggish streams, usually over mud (Ref. 10294, 58020). Oviparous, eggs are deposited in aquatic vegetation, preferably on strands of Ceratophyllum sp. When available (Ref. 58020). Feed on microcrustacea together with midge larvae, larger crustacea (isopods and amphipods), mayfly nymphs, and small snails and clams (Ref. 10294).

Estimates of some properties based on empirical models
Phylogenetic diversity index (Ref. 82805
= 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01120 (0.00513 - 0.02445), b=3.04 (2.87 - 3.21), based on all LWR estimates for this BS (Ref. 93245
Trophic Level (Ref. 69278
): 3.7 ±0.4 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278
