A few years ago, P. obscura was recognized as a separate species of guppy from Trinidad. They are endemic to rivers on the eastern side of the island. While it is easy to tell them apart from guppies when you look at the DNA, telling them apart morphologically is a bit more challenging.

They tend to be smaller than other types of guppies from the same area, with a body that is a bit stockier than the guppies’. Also, males usually have one to three black spots, one of which is on the caudal peduncle. Again, they are much smaller than guppies, with males barely reaching ¾ inch (2 cm) and females barely topping an inch (2.5 cm).

In addition, at least with the La Seiva River population, while the males from the same broods are polymorphic and no two males look exactly alike, they also tend to have pastel coloration of blues, oranges, and pinks. Finally, the dorsal fin is rounded in shape and clear, while in guppies it is often replete with colors and fin ray extensions.

Around Dangriga, Belize the males come in 3 colors, red, yellow and "clear." The latter is usually the most common. But in mangrove habitats every school had a few red males. They were very conspicuous to me, and I would bet also to avian predators. - Bruce Turner

Although Innes included the liberty molly in Exotic Aquarium Fishes, most subsequent writers have regarded it as a mere variety of Poecilia sphenops, the common molly. Only recently has the liberty molly been recognized as something distinct, and this very pretty livebearer is now increasingly regularly traded.

This species has very lovely colors. Both sexes are silvery white with orange and blue speckles, but while the females have rather weak colors on their fins, the males have fins that are boldly marked with black, neon blue, and either burgundy or yellow depending on the morph. The burgundy one is most often traded, and the combination of red, white, and blue is presumably where the liberty molly name comes from. Coloration improves with age, and older, dominant males have large, almost sail-like dorsal fins and intense coloration.

But while the small livebearers mentioned so far have been more or less peaceful, community-safe fish, the liberty molly can be very nippy and aggressive. Actually, most other kinds of mollies can be quite nasty toward their tankmates as well, something beginners often learn the hard way. While liberty mollies are supremely attractive fish in many ways, they aren’t for everyone, and they’re definitely best kept alone in a tank of their own.

Males will fight relentlessly in small tanks, and if there are only two males in the group, the weaker one will likely be bullied to death. Keep liberty mollies in groups where females outnumber males two to one, and keep either just a single male or at least three.

As with all mollies, this species is primarily herbivorous and does well on algae-based flake food. Their maximum length is about 3 inches, with males being generally smaller than females. A 30-gallon tank should be adequate for a group of three males and six females. Like most other mollies, this species is jumpy and shouldn’t be kept in an open-top aquarium. - Neale Monks
