Description

Overview and Origin
  • Scientific Name: Derived from species in the genus Poecilia (such as Poecilia sphenops and Poecilia latipinna).

  • History: The solid black variety was developed through selective breeding in the 1920s and 1930s, and has been a staple in the aquarium hobby since.

  • Size: Males grow up to about 6 cm (2.4 inches), while females grow slightly larger, up to 8 cm (3.2 inches).

Tank Care and Requirements

  • Water Temperature: Keep between 24°C and 28°C (75°F to 82°F).

  • Water Chemistry: Prefer hard, alkaline water (pH 7.2–7.7). They are sensitive to soft water, rapid parameter shifts, and poor filtration.

  • Salt Addition: Many hobbyists add a small amount of aquarium salt (around 1 tablespoon per 10 liters) to mimic their natural brackish tolerance and keep them healthy.

  • Diet: Omnivorous with a strong preference for plant matter. They eat algae, spirulina, flakes, and occasional live or frozen foods.

Breeding

  • Reproduction: They are livebearers, meaning eggs hatch internally and females give birth to free-swimming fry.

  • Brood Size: Can produce up to 100+ young per birth cycle.
