Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 9 - 10; Anal soft rays: 13 - 15; Vertebrae: 31 - 32. Possession of greenish blue bars on the ventrolateral portion of the posterior half of male body side; triangular dark gray suborbital mark; scales in the longitudinal series 31-32; anal fin rays 13-15; and absence of an ocellate spot on the caudal fin base in both sexes (Ref. 52503).

Inhabits clear water streams within forest at about 50 cm deep (Ref. 52503). Not a seasonal killifish. Is difficult to maintain in aquarium (Ref. 27139).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5039 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.2 ±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.).

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