The Balloon Molly (Poecilia latipinna) is a variant of the common Sailfin Molly, selectively bred for its distinct, rounded body shape. This peaceful, social fish is one of the best choices for beginner aquarists, offering a blend of beauty, resilience, and easy care.

🌊 Appearance

Balloon Mollies feature a shortened body and arched back, giving them their characteristic balloon-like appearance. Available in various colors — black, gold, dalmatian, and marble — they add vibrant charm to community aquariums.

🐟 Behavior & Compatibility

These fish are peaceful and social, best kept in small groups (3 or more). They coexist well with other calm species like guppies, platies, swordtails, and tetras. Males may occasionally chase females, so maintaining a 2:1 female-to-male ratio helps reduce stress.

🏡 Aquarium Requirements

Balloon Mollies thrive in well-aerated tanks with stable water conditions. A minimum of 20 gallons is recommended to allow ample swimming space. They prefer slightly alkaline water and benefit from the addition of aquarium salt to mimic their natural brackish environment.

Include live or artificial plants, smooth gravel, and moderate water flow. Regular water changes are essential for their health and vibrant coloration.

🍽 Feeding

As omnivores, Balloon Mollies enjoy a varied diet:

• High-quality flake or pellet food

• Blanched vegetables (zucchini, spinach, peas)

• Occasional treats of brine shrimp or daphnia

Feed small portions 2–3 times daily to prevent overfeeding.

🧬 Breeding

Like other livebearers, females give birth to live fry rather than laying eggs. Breeding occurs easily in home aquariums; however, providing dense plants or breeding boxes helps protect fry from adult fish.

🩵 Care Tips for Beginners

• Maintain consistent water temperature with a reliable heater.

• Avoid overcrowding — Balloon Mollies need space to swim comfortably.

• Perform weekly 25–30% water changes to ensure cleanliness.

• Observe fish regularly for signs of stress or illness.
