Description
The Black Lyretail Molly is a selectively bred form of the popular Poecilia sphenops, renowned for its long, ribbon-like lyretail and velvety black body. This fish brings sophistication to any planted or community tank and is especially popular for aquascapes, modern aquariums, and minimalist setups. Its deep black scales contrast beautifully with green plants, colorful tankmates, and light substrates.
Black lyretail mollies grow to an adult size of 3–4 inches (7.5–10 cm). Their most defining feature is the elegant, elongated tail fin that sweeps behind them as they swim, creating a graceful, flowing look. The all-black body and fins make this Molly fish a dramatic centerpiece in both nano and mid-sized aquariums.
Lyretail mollies are peaceful, active, and highly adaptable. They thrive in community tanks with other gentle fish such as Tetras, Platies, Fancy Guppy, Swordtails, Corydoras, and freshwater shrimp. As livebearers, they may produce fry if males and females are kept together, making them a great choice for hobbyists interested in breeding.
