Distribution Countries | FAO areas | Ecosystems | Occurrences | Point map | Introductions | Faunafri

Central and South America: Pacific drainage system from Darien, Panama to Rio Cauca, Colombia as well as in Lake Maracaibo, Venezuela. Known from the Catatumbo River (Ref. 26543).

Size / Weight / Age

Maturity: Lm ?  range ? - ? cm
Max length : 3.0 cm TL male/unsexed; (Ref. 26543); 6.0 cm NG (female)

Short description Identification keys | Morphology | Morphometrics

Identified by the black spot found on the base of the dorsal fin; some specimens with thin transverse bands along the body but this may be attributed to the coloration before or after the reproductive period (Ref. 26543).

Biology     Glossary (e.g. epibenthic)

Feeds on algae and insects end up in the water (Ref. 26543). Tolerates extreme temperature, salinity and anoxia conditions (Ref. 26543). There was a proposal to use this species as biological control against mosquito larvae (Ref. 26543).

Life cycle and mating behavior Maturities | Reproduction | Spawnings | Egg(s) | Fecundities | Larvae

Produces 10 to 25 young after a gestation period of about 28 days. Young cared for by the male (Ref. 26543).

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=0.01318 (0.00562 - 0.03093), b=3.14 (2.96 - 3.32), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  2.6   ±0.26 se; based on food items.
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).
