Poecilia caucana és un peix de la família dels pecílids i de l'ordre dels ciprinodontiformes.
Els mascles poden assolir els 3 cm de longitud total i les femelles els 6.[2]
Es troba als rius de la costa pacífica des de Panamà fins a Colòmbia. També al llac Maracaibo (Veneçuela).[3]

The Cauca molly (Poecilia caucana) is a freshwater fish in the family Poeciliidae.[2] This fish is found in Panama, Venezuela, and Colombia, where it lives in shallow waters in the basins of the Lebrija, Magdalena, Cauca and other rivers.[3][4] P. caucana eats mosquito larvae and algae.
The male Poecilia caucana grows to a length of 3 cm (1.2 in) while the female can attain 6 cm (2.4 in). Generally silvery in colour, this fish can be identified by the black blotch at the base of the dorsal fin. Some specimens show some degree of narrow transverse banding, but this may be the lingering remains of colour changes associated with breeding.[2]
P. caucana is native to freshwater systems in tropical Central and South America. Its range extends from the east-flowing rivers of Panama to the Cauca River in Colombia. Its range also includes the Catatumbo River in northern Colombia, and Lake Maracaibo in Venezuela into which it flows. This fish is a very tolerant species, able to withstand considerable variations in temperature and salinity, as well as low levels of oxygen.[2]
An omnivore, P. caucana feeds on algae, on mosquito larvae and on insects that fall onto the water surface.[2] Proposals have been made to use this species, as well as the closely related guppy (Poecilia reticulata),[5] in biological pest control of mosquitoes.[6] The Cauca molly is a livebearer; the female produces a batch of ten to twenty-five live young after a gestation period of about four weeks.[7] The juvenile fish are cared for by the male.[2]
This fish is sometimes kept in aquaria. It does best at temperatures of between 27 and 29 °C (80.6 and 84.2 °F) in well-aerated conditions at a pH of 7.0 to 7.5.[7]

Poecilia caucana, communément appelé Molly de Cauca[3], est une espèce de poissons d'eau douce de la famille des Poeciliidae.
Poecilia caucana habite les eaux peu profondes du Venezuela, du Panamá et de la Colombie. Il préfère les endroits où la végétation est abondante.
Poecilia caucana mesure 3-4 cm. La femelle est plus ronde et plus grosse que le mâle. Le corps en entier est de couleur bleu-gris, à l'exception de la nageoire dorsale qui présente une tache jaune et une tache noire. Le mâle se différencie facilement de la femelle par la présence d'un gonopode (nageoire anale modifiée servant à la reproduction).
La température de l'eau dans son habitat naturel se situe entre 22 et 25°C et le pH entre 6,5 et 7,2.
Poecilia caucana se nourrit de végétaux, d'algues et de larves de moustiques.
