Biology     Glossary (e.g. epibenthic)

Occurs in vegetated standing water bodies and quiet pools and backwaters of streams (Ref. 5723, 10294). Maximum length 7.8 cm TL (Ref. 5723). Feeds on terrestrial insects, snails, small crustaceans, and some algae (Ref. 10294). 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 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00468 (0.00176 - 0.01240), b=3.15 (2.92 - 3.38), based on LWR estimates for this (Sub)family-body shape (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) .
