Molly Balloon Red

Red Balloon Molly is a selectively bred variant of Poecilia sphenops, known for its vibrant red coloration and distinctive rounded body shape. This livebearing fish is a favourite among aquarists due to its peaceful temperament, active swimming behaviour, and striking appearance. The balloon body shape is the result of a genetic modification that shortens the spine, giving the fish a compact, arched profile. While visually appealing, this trait requires careful husbandry to ensure long-term health. Features of Red Balloon Molly • Grows up to 6–8 cm in length • Distinctive rounded body with a deep arch and short snout • Bright red to orange-red coloration, often uniform across the body • Livebearer; females give birth to free-swimming fry • Generally peaceful and social; thrives in groups • Lifespan ranges from 3–5 years with proper care The best aquarium size for Red Balloon Molly A minimum of 60 litres is recommended for a small group (3–5 individuals). Larger tanks (100 litres or more) are ideal to support stable water parameters, reduce aggression, and allow space for swimming. Provide open swimming areas along with planted zones for shelter and comfort. Tank Mate Compatibility for Red Balloon Molly • Guppies • Platies • Corydoras catfish • Zebra Danios • Swordtails Diet for Red Balloon Molly Red Balloon Mollies are omnivorous and benefit from a balanced diet. Offer high-quality flakes or micro pellets as a staple. Supplement with blanched vegetables (zucchini, spinach), spirulina flakes, and occasional frozen or live foods like daphnia or brine shrimp. A varied diet enhances colour and immune function. Aquarium Setup Red Balloon Molly Aquarium Filtration Use a gentle yet effective internal or hang-on-back filter. Mollies produce moderate waste, so efficient biological and mechanical filtration is essential. Maintain ammonia and nitrite at 0 ppm, and keep nitrate below 30 ppm. Aquarium Plants Live plants such as Java fern, Anubias, Vallisneria, or Hornwort are well suited. Plants provide shade, help with water quality, and create natural cover for fry. Aquarium Lighting Moderate lighting enhances the vibrant red colours and supports plant growth. Avoid overly intense lighting, which can stress fish and encourage algae. Aquarium Heating Maintain a consistent temperature between 24–27 °C. Use a reliable heater with a thermostat, and avoid rapid fluctuations. Aquarium Substrate Use fine gravel or sand substrate. Balloon Mollies don’t dig extensively but benefit from smooth, soft surfaces that are gentle on their fins and bellies. Aquarium Decorations Incorporate smooth rocks, driftwood, and plants to provide visual interest and hiding spots. Avoid sharp decor that could injure their delicate, rounded bodies. Leave open space for swimming, especially in the mid and upper levels of the tank.
