  Physical Description:

  • Size: 3 to 5 inches (7.5 to 12 cm) depending on the variety.
  • Shape: Sleek, slightly flattened body with a rounded belly (especially in pregnant females).

    • Dorsal fin: Tall and fan-like in males, shorter in females.
    • Caudal fin (tail): Can be rounded, lyre-shaped, or sail-shaped in some varieties.
  • Colors & Patterns:
    • Wild mollies are usually silvery-gray or greenish.
    • Captive-bred varieties come in black (Black Molly), gold, white, dalmatian (spotted), and even metallic shades.
    • Some have lyre tails or balloon-shaped bodies (selectively bred).

  Behavior & Temperament:

  • Peaceful & Social: Gets along well with other community fish like guppies, platies, and tetras.
  • Active Swimmers: Prefer swimming in the middle to upper levels of the tank.
  • Livebearers: Females give birth to free-swimming fry (no eggs).

  Habitat & Care Requirements:

  • Water Conditions:
    • Temperature: 72–82°F (22–28°C)
    • pH: 7.5–8.5 (slightly hard, alkaline water preferred)
    • Salinity: Some varieties tolerate brackish water.
  • Tank Size: Minimum 10–20 gallons (larger for groups).

  Popular Molly Varieties:

  1. Black Molly – Solid black, one of the most common.
  2. Dalmatian Molly – White with black spots.
  3. Balloon Molly – Rounder, shorter body (controversial due to health concerns).
  4. Sailfin Molly – Larger dorsal fin (males).
  5. Gold Dust Molly – Golden-yellow with black speckles.

  Breeding:

  • Easy to breed (females can store sperm and produce multiple batches from one mating).
  • Gestation: 4–6 weeks, yielding 20–100 fry.
  • Fry Care: Need hiding spots (plants) to avoid being eaten by adults.

  Mollies are great for beginners but do best in stable water conditions with some salt (optional). Their lively personalities and variety of colors make them a delightful addition to community tanks! 🐟💙
