The Balloon Molly (Poecilia latipinna or Poecilia sphenops selectively bred variety) is a small, peaceful livebearer fish known for its rounded, balloon-like body shape. Popular in community aquariums, Balloon Mollies thrive in well-planted tanks with stable water conditions, open swimming space, and a gentle current. They prefer slightly brackish to freshwater environments with stable parameters and do best in groups, as they are social and active. Their diet should include high-quality flakes or pellets, supplemented with algae-based foods, vegetables like blanched spinach or zucchini, and occasional protein treats such as brine shrimp or bloodworms. Balloon Mollies are hardy but sensitive to poor water quality due to their altered body shape, so clean, well-maintained aquariums are essential. As prolific livebearers, they breed readily, so providing hiding spots or separating fry is necessary if survival of young is desired.
