Gold Black Lyretail Molly (Poecilia sphenops) is a selectively bred livebearer with a gold front, black rear patterning and a flowing lyre-shaped tail. It is a strong choice for keepers who want colour and movement in a hard-water community aquarium without forcing a delicate soft-water species into unsuitable conditions.

Mollies need stable, mineral-rich water, open swimming space and clean filtration. Keep them in a small social group and avoid cramped soft-water nano tanks. Plants, floating cover and a calm current help them settle.
Use quality flakes, micro pellets, spirulina foods, blanched greens and occasional frozen foods such as daphnia or brine shrimp. A vegetable-rich diet helps digestion and condition.
Choose peaceful livebearers and other hard-water community fish. Useful comparisons include Silver Sailfin Molly, Green Sail-Fin Molly Pair, Green Moscow Male Guppy, Koi Kohaku Swordtail and Sunset Simpson Variatus Platy.
