Reproductive frequency (?) | Iteroparous References (not structured): Reznick, D. N., Rodd, F. H., Cardenas, M. 1996. Life-history evolution in guppies (Poecilia reticulata: Poeciliidae). IV. Parallelism in life-history phenotypes. The American Naturalist, 147(3), pp. 319-338. |
Reproductive type (?) | Sexual References: Shahjahan, R. M., Ahmed, M. J., Begum, R. A., Rashid, M. A. 2013. Breeding biology of guppy fish, Poecilia reticulata (Peters, 1859) in the laboratory. Journal of the Asiatic Society of Bangladesh, Science, 39(2), pp. 259-267. Reznick, D. N., Rodd, F. H., Cardenas, M. 1996. Life-history evolution in guppies (Poecilia reticulata: Poeciliidae). IV. Parallelism in life-history phenotypes. The American Naturalist, 147(3), pp. 319-338. Comments: Males are about half the size of females with colorful tail and caudal fin; the anal fin is transformed into a gonopodium for internal fertilization. Males are continuously chasing and mating females. Females can store sperms for later fertilization and may produce young every four weeks. Pregnant females are recognizable by black triangle between anal and pelvic fins. After a gestation period of four to six weeks females give birth to 20-40 live young. |
Developmental trait (?) | Viviparous References: Shahjahan, R. M., Ahmed, M. J., Begum, R. A., & Rashid, M. A. (2013). Breeding biology of guppy fish, Poecilia reticulata (Peters, 1859) in the laboratory. Journal of the Asiatic Society of Bangladesh, Science, 39(2), 259-267. Comments: They are ovoviviparous, which means they give birth to live, well-formed young. A female guppy can give birth to several dozen cubs in one litter. |

Contrasting population and diet influences on gut length of an omnivorous tropical fish, the Trinidadian guppy (Poecilia reticulata). PLoS One, 10(9), e0136079. Dussault, G. V., Kramer, D. L. 1981. Food and feeding behavior of the guppy, Poecilia reticulata (Pisces: Poeciliidae). Canadian Journal of Zoology, 59(4), pp. 684-701. Comments: P. reticulata fed mainly on algae, organic detritus, diatoms, mosquito larvae parts, protozoan, zooplankton and fish parts while algae form the most abundant and important food item. |
Mobility / Life stage (?) |
|
Salinity tolerance range (?) | Exact range: 0 - 28 References: Pethiyagoda, P. D. R., De Alwis, S. M. D. A., De Silva, B. G. D. N. K. 2019. Salinity tolerance of wild Poecilia reticulata (guppy) under laboratory conditions. International Journal of Multidisciplinary Studies, 6 (2), pp. 1-7. Comments: The present study indicates that guppy taken from wild populations are able to tolerate a direct exposure of 28 ppt salinity with 50 % mortality but they show 100% mortality beyond this level, while they can tolerate salinities upto 38ppt if the salinity levels increase gradually showing only 20% mortality. |
Habitat modifying ability potential (?) | Unknown Comments: Not available. |
Toxicity / Life stage (?) | Not relevant |

Known human health impact? | Known References: Kušar, D., Zajc, U., Jenčič, V., Ocepek, M., Higgins, J., Žolnir-Dovč, M., Pate, M., 2017. Mycobacteria in aquarium fish: results of a 3-year survey indicate caution required in handling pet-shop fish.Journal of Fish Diseases, 40(6), pp. 773-784. Monticini, P., 2010. In: The ornamental fish trade: Production and commerce of ornamental fish: Technical-managerial and legislative aspects. Rome, Italy: FAO GLOBEFISH Research Programme. ix + 134 pp. Comments: Ornamental guppies have been shown to carry several species of mycobacteria, which can cause pathology in immunocompromised humans. |
Known economic impact? | Known References: Deacon, A. E., Ghosh, S. K., Bhat, A., Magurran, A. E. 2019. Predatory behaviour of female guppies (Poecilia reticulata) in a mosquito control context: the importance of social and habitat factors. Aquatic Invasions, 14(3), pp. 478-489. Comments: P. reticulata to prey on the larvae of many freshwater species, it may prey on the larvae of species with economic value. P. reticulata, have been introduced widely outside of their native range for mosquito control. |
Known measurable environmental impact? | Known References: Deacon, A. 2023. Poecilia reticulata (guppy). CABI Compendium. Available at: https://www.cabidigitallibrary.org/doi/full/10.1079/cabicompendium.68208 (Accessed: 22 July 2024). Comments: Guppies breed rapidly and therefore can outcompete native species for food and space, especially other small fishes. P. reticulata is also a known carrier of a number of diseases that can spread to native fish species. |
