Guppy - Poecilia reticulata: Poeciliidae: pesci di acqua dolce(Site not responding. Last check: 2007-10-10)
Poeciliareticulata è certamente più famoso con le definizioni guppy, lebistes, pesce milione, ma il suo vero nome con cui risulta nella nomenclatura scientifica è proprio questo: Poeciliareticulata.
Il Poeciliareticulata è un pesce assolutamente pacifico, che ama vivere in gruppi.
Come per quasi tutti i pesci appartenenti alla famiglia dei Poeciliidae, anche i Poeciliareticulata sono ovovivipari, e quando le femmine sono gravide si nota una evidente macchia scura in prossimità della pinna anale.
The Trinidadian guppy, Poeciliareticulata, represents one of the best vertebrate models for the study of how phenotypic variation within a population is linked to adaptation to specific environmental conditions.

The project comprizes cloning of candidate genes known to be involved in regulation of pigment patterns of other vertebrates, identification of neural crest cells in embryogenesis by means of in situ hybridization, genetic and molecular analysis of genes involved in pigmentation.
It can occupy a wide range of aquatic habitats and is a threat to native cyprinids and killifishes, a carrier of exotic parasites, and is believed to play a role in the in the decline of several threatened and endangered species.
reticulata males are smaller, reaching an average length of 3.5 cm compared 5 cm in females.
reticulata and Xiphophorus helleri are shown to threaten species of native fish in the western USA (Courtenay and Meffe, 1989 in Eldredge, 2000).
reticulata, by exposing the fish to a potentially threatening stimulus (a red-tipped metrestick extended towards the individual) and a non-threatening stimulus (a novel food source).

The species has been placed in the Poecilia subgenus Acanthophacelus, which was originally erected by Eigenmann in 1907, and according to the authors, it is very closely related to the common guppy, Poeciliareticulata.
Poecilia wingei is found in the Campoma region of Venezuela, at the base of the Paria Peninsula.
The authors don't categorically state in the paper that Poecilia wingei is exactly the same species as the fish on sale in the trade as the Endler's livebearer, however, this does seem a plausible identity for the fish.
Er berichtete, dass er auf Barbados Poecilia poeciloides in ungeheuren Mengen fand, auf Trinidad Giardinus guppyi und auf den venezolanischen Festland Poeciliareticulata.
Der Fisch wurde als Poeciliareticulata Peters zuerst angeboten, bis er seinen heutigen Namen erhalten hat.
Die richtige Poeciliareticulata soll ebenfalls importiert sein.

Derived from the wild species Poeciliareticulata (originally from Central/South America) it is small, beautiful, peaceful, lively and generally hardy.
Better yet, there's a myriad of colorful variants that can be collected and easily bred, so the guppy is one of the best choices for beginners in the hobby, especially children.
El guppy (Poeciliareticulata) es un pez ovovivíparo de agua dulce procedente de Centroamérica que habita en zonas de corriente baja de ríos, lagos y charcas.
Es muy conocido en el mundo de la acuariofilia puesto que su cuidado no ofrece grandes dificultades y se reproduce con muchísima facilidad.
La primera de ellas fue un zoólogo llamado Peters, que en 1859 la bautizó con el nombre de Poeciliareticulata, seguido de De Filippi, en 1963 que la volvió a descubrir, pero dándole el nombre de Lebistes poeciloides.
My main research is on the molecular sytematics and sexual selection in the guppy (Poeciliareticulata) and closely related species (Poecilia parae, Poecilia picta, and undescribed species), from northeast South America.
It is well documented that several chemicals from agricultural, industrial, and household sources possess endocrine-disrupting properties, which potentially pose a threat to human and wildlife reproduction (1,2).

Being quite hardy and easy to acclimate, PoeciliaReticulata is a great fish for beginners as well as experienced hobbyist looking to create their own Fancy Guppy species.
Notes: PoeciliaReticulata is certainly the most common fish in aquariophilia.
Its easiness to keep and breed as well as its beautiful colors and shapes make it very popular in aquariums.
We investigated the ability to recognize the color of surfaces in fish (Poeciliareticulata), bred from birth in conditions of artificial light with constant spectral content.
The capacity for color constancy significantly deteriorated when compared that to the control group.
