General Information

Dalmatian Balloon Mollies are hardy and adaptable, thriving in various water conditions as long as they are kept in groups. Their balloon-shaped body is a result of selective breeding, though this can sometimes come with health considerations related to their body shape. It’s important to ensure they are not overfed to prevent obesity and related issues.

A Fun Fact

Despite their “balloon” shape, Dalmatian Balloon Mollies are active swimmers. They may appear round, but they’re quite energetic and enjoy exploring every corner of their tank!
