(178) Black Balloon Molly

The black balloon molly (Poecilia sphenops or Poecilia latipinna) is a selectively bred variation of the popular molly fish, known for its rounded body and jet-black coloration. They are generally peaceful and hardy, making them a popular choice for community aquariums, though some sources suggest beginners need to be careful to provide stable water conditions. 

• Minimum tank size: A minimum of 20 gallons is recommended, providing plenty of swimming space. Overcrowding can cause stress and aggression.
• Water parameters: Aim for a temperature range of 75 to 82°F (24 to 28°C), a pH between 7.5 and 8.2, and moderately hard to hard water. Stable water parameters are important for their health.
• Decorations: These fish appreciate a planted tank with both open areas for swimming and places to hide, such as live plants, rocks, or driftwood. 

• Omnivorous diet: Feed them a balanced diet of both plant and animal-based foods, such as high-quality flakes or pellets.
• Supplements: Supplement their diet with algae-based foods, blanched vegetables like peas and zucchini, and protein-rich treats like brine shrimp. 

• Social fish: Mollies are social and should be kept in a group of at least 4 to 6 individuals. Keeping a ratio of at least two females per male can help prevent harassment by males.
• Peaceful temperament: They are peaceful but should be housed with other non-aggressive tank mates. Avoid fin-nipping species or large, predatory fish.
• Livebearers: As livebearers, they will readily breed in a community tank. If you want to protect the fry, provide plenty of hiding spots or use a separate breeding box. 

• Sensitive to water quality: Like all mollies, they cannot tolerate even small amounts of ammonia and nitrite. Regular water changes and a high-quality filter are crucial.
• Potential health issues: The compressed spine from selective breeding can lead to swim bladder problems or digestive difficulties. A varied diet with plenty of fiber can help.
