Size / Weight / Age

Maturity: L_m ? range ? - ? cm
Max length : 4.5 cm SL male/unsexed; (Ref. 26130); 5.0 cm SL (female)

Inhabits a quiet pool of clear to murky water at a depth of up to 1.2 m and with bottom consisting of sand, silt, rocks and boulders.

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Viviparous. Males possess an andropodium, a structureless lobule of the anal fin which acts only as conveyor to assure successful fertilization.

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 2.1 ±0.1 se; based on size and trophs of closest relatives

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