Short description पहचान कुंजी | आकृति विज्ञान | मौरफोमैटरिक्स

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).

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).

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.

लौटाव (Ref. 120179): ऊंचा, न्यूनतम जनसंख्या दुगनी समय अवलागत 15 महीने। (Preliminary K or Fecundity.).

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