Short description Chiavi di identificazione | Morfologia | Morfometria

Spine dorsali (totale) : 0; Raggi dorsali molli (totale) : 11 - 14; Spine anali: 0; Raggi anali molli: 8 - 10. This species is distinguished by having a medium to large swordtail with a long straight caudal appendage; midlateral stripe may be dusky or brownish (northern populations) or red; 2 additional reddish stripes may be present above midlateral line and one beneath; terminal segment of gonopodial ray 3 produced into a crescent-shaped hook and blade pointed distally; ray 4a curves strongly backward over the blade at an angle greater than 90°; distal serrae of ray 4p reduced in size and number and proximal serrae rather slender; terminal segment of ray 5a produced into a claw, several times larger than the distal serrae of ray 4p (Ref. 52914).

Biologia     Glossario (es. epibenthic)

Adults are found mainly in rapidly flowing streams and rivers, preferring heavily vegetated habitats (Ref. 26130). They occur in warm springs and their effluents, weedy canals and ponds (Ref. 5723). They feed on worms, crustaceans, insects and plant matter (Ref. 7020). Used for genetics research (Ref. 4537). Especially the red varieties are very popular aquarium fishes (Ref. 1672). Aquarium keeping: the males aggressive towards each other; minimum aquarium size 80 cm (Ref. 51539).

Life cycle and mating behavior Maturities | Riproduzione | Spawnings | Egg(s) | Fecundities | Larve

Female produces 20 to 200 young after a gestation period of 24 to 30 days. Attains sexual maturity after eight to twelve months (Ref. 26130). This species has a tendency to undergo sex reversal (from female to male) under certain environmental conditions (Ref. 6465).

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=0.01000 (0.00606 - 0.01650), b=3.05 (2.92 - 3.18), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level (Ref. 69278):  3.2   ±0.43 se; based on food items.
Resilienza (Ref. 120179):  Alto, tempo minimo di raddoppiamento della popolazione meno di 15 mesi (tm<1; Fec=20-200 * 12).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
Price category (Ref. 80766):   Unknown.
