Assorted Lyretail Balloon Molly

The Assorted Lyretail Balloon Molly is a captivating freshwater fish known for its vibrant colors and unique tail fin. It’s a popular choice for home aquariums due to its peaceful nature, ease of care, and lively presence.

Scientific Name: Poecilia sphenops [var.] Balloon Lyretail

Water Quality

These Mollies thrive in well-maintained aquariums with consistent water parameters. Here’s a breakdown of their ideal water conditions:

  • Temperature: 72°F – 82°F (22°C – 28°C)
  • pH Level: 7.5 – 8.5 (slightly alkaline)
  • GH Level: 10 – 20 dGH (moderately hard water)
  • KH Level: 8 – 12 dKH (moderately high carbonate hardness)


Assorted Lyretail Balloon Mollies are omnivores and enjoy a varied diet. Provide a mix of high-quality flake food, algae wafers, and occasional treats like brine shrimp or bloodworms. Supplement their diet with fresh vegetables like blanched spinach or zucchini for optimal health.

Tank Mates

These peaceful fish make excellent additions to community tanks with other peaceful inhabitants. Good tank mates include:

  • Guppies
  • Platies
  • Swordtails
  • Corydoras catfish
  • Neon tetras

Avoid keeping them with aggressive fish or fin nippers like Barbs or Cichlids.

Substrates and Tank Decorations

  • Substrate: Opt for a smooth gravel substrate to prevent damage to their delicate fins.
  • Decorations: Provide hiding places with rocks, driftwood, and live or silk plants.

Suitable Plants

Live plants offer hiding spots, grazing opportunities, and help maintain water quality. Choose hardy plants that can tolerate brackish conditions (slightly salty water) as Mollies are adaptable. Some good options include:

  • Java Fern
  • Hornwort
  • Water Sprite
  • Anubias

Sexing and Breeding

Males are typically more colorful and have a larger, fancier Lyretail fin (the tail resembles a lyre). Females are rounder and have a shorter, simpler tail fin. Mollies are prolific breeders. Females can store sperm for months, allowing them to give birth to live fry even after being separated from males.

Maximum Size and Longevity

  • Size: 2 – 3 inches (5 – 7.5 cm)
  • Longevity: 3 – 5 years with proper care


Assorted Lyretail Balloon Mollies are peaceful and social fish. They enjoy swimming in groups and add a splash of color to the aquarium. The males can display playful aggression towards each other, but it’s rarely harmful.

Things to Consider Before Buying

  • Tank Size: These fish require a minimum of a 20-gallon tank to provide enough space for swimming.
  • Brackish Tolerance: While they can adapt to slightly salty water, freshwater is perfectly suitable for them.
  • Peaceful Tank Mates: Avoid housing them with aggressive fish.

General Information

Mollies come in a wide range of vibrant colors, including black, orange, yellow, white, and a combination of these. Their rounded bodies and flowing Lyretail fins make them a captivating addition to any aquarium.

Fun Fact

The “balloon” in their name refers to their short, round bodies, a result of selective breeding. This gives them a somewhat stocky appearance compared to other Molly varieties.
