Acquired: Fish / pet store
Posted Jul 09, 2014
The Swordtails are cousins to Platys. They are mostly herbivores; although this species is originally green, the most common specimens you are going to find are of the orange variety. A native of Mexico, this species is distinguished by the beautiful sword tail. They prefer brackish water, but they’ll live well in freshwater as well (much like the guppies). The male reaches 3.5 inches and the female up to 4.2 inches. Their reproduction is easy, like most livebearers, not always show available to show us their mating rituals. The Swordtails live, as befits the Poeciliidae family, near the surface of the fish tank. In pet stores there are several sub-species obtained by selection and you may find red, yellow and black variations. Extremely sociable, they should do well in community tanks with Guppies, Mollies and Platys, but males might get aggressive towards each other, so it is better to keep a proportion of 3 females to 1 male, to avoid rough mating disputes. Slightly alkaline water, or even neutral pH, is recommended for them, as well as a minimal temperature of 77F.
