Size / Weight / Age

Maturity: L_m ? range ? - ? cm
Max length : 6.0 cm TL male/unsexed; (Ref. 27139); common length : 3.3 cm TL male/unsexed; (Ref. 12193)

Inhabits shallow, sandy pools and runs of headwaters, creeks, and small to medium rivers. Often found in extremely shallow and hot (to 37°C) water (Ref. 5723). Consumes midge and other insect larvae (Ref. 79012). Not a seasonal killifish. Is difficult to maintain in aquarium (Ref. 27139).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01349 (0.00591 - 0.03081), b=3.14 (2.95 - 3.33), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 2.6 ±0.1 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (Assuming tm<1).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).

Price category (Ref. 80766): Unknown.
