Biology     Glossary (e.g. epibenthic)

Inhabits vegetated quiet water and usually swims several inches below surface of water. 7 cm max TL (Ref. 5723). Feeds on larval crustaceans (mainly cyclopoid and harpacticoid copepods), mosquito larvae, small worms, and mollusks (Ref. 79012). Not a seasonal killifish. Is difficult to maintain in aquarium (Ref. 27139).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.6250   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02512 (0.01220 - 0.05171), b=3.28 (3.10 - 3.46), in cm Total Length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic Level (Ref. 69278):  3.2   ±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):  Low vulnerability (10 of 100) .
