The original Platy (Xiphophorus Maculatus), and the Variatus Platy (Xiphophorus Variatus) have been interbred for many years, so the varieties generally available for sale are not true purebreds of the species. There are thought to be at least 40 different hybrids and selected forms of Platys around, including the popular Red, Sunset and Tuxedo varieties.
Platys like to live in an aquarium with some areas of dense vegetation, along with areas of open water for swimming.
The male and female Platys are easy to distinguish from each other, as the male is smaller, and has a gonopodium (a modified anal fin).
Like most livebearers, Platys are very easy to breed, and for that reason are ideal for beginners. Keeping at least 2-3 females for each male will help ensure the female Platys aren’t harassed too much.
When breeding
, the female Platy will give birth to anywhere from 20 to 150 live young, after a gestation period of four to six weeks. These young Platys are free swimming from the outset, and will grow rapidly, reaching sexual maturity in six or eight months, and will be fully grown in a year.
To ensure the best survival rate, it is best to remove the female Platy from the main aquarium and move her to a nursery aquarium before she gives birth. A few young Platys may survive in a community tank if there are sufficient plants for them to hide in, but generally most of them will get eaten, either by their parents or the other occupants of the aquarium.
