Teleostei (teleosts) > Cyprinodontiformes (Rivulines, killifishes and live bearers) > Goodeidae (Splitfins) > Goodeinae
Etymology: Allotoca: Greek, allos = other + Greek, tokos = birth (Ref. 45335). The transliterated Latin terminal part of the compound name ('tocus') was changed to 'toca', thus the genus is feminine (Ref. 35111).

Environment: milieu / climate zone / depth range / distribution range Ecology

Freshwater; demersal; pH range: 7.0 - 7.6; dH range: 5 - 20. Tropical; 21°C - 25°C (Ref. 12468)

Size / Weight / Age

Maturity: L_m ? range ? - ? cm
Max length : 7.5 cm SL male/unsexed; (Ref. 26130); 8.5 cm (female)

Inhabits slow flowing water with dense algal growth on rocks. Also occurs in swamps (Ref. 26130).

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

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

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): 2.2 ±0.1 se; based on size and trophs of closest relatives

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