A pet fish that’s great for beginner aquarists with its hardy characteristic, beautiful and colorful appearance, ideal temperament, and interesting features. The Balloon Belly Molly originates in the east coast of Florida, North Carolina, and the Gulf of mexico. This cool fish is a livebearer and does not give birth to eggs, rather produces an offspring of cute, tiny little fishes.

Did you know that mollies have the ability to adapt to varied salt levels within the aquarium? They can be maintained in either a freshwater or saltwater aquarium provided there is gradual acclimation. For the freshwater aquarium, adding a teaspoon of aquarium salt per gallon of water is recommended for your pet Balloon Belly Molly’s optimum health.


An arched back, rounded huge belly, a large seemingly lyre-shaped caudal fin, and remarkable dorsal fin define the predominant traits of the Black Belly Molly. They arrive in a combination of black, white and yellow colors that exhibit varied patterns, rendering them very attractive pet fishes to keep that will enhance any aquarium setting.
