What Balloon Molly look like

The Balloon Molly is a domestic short-bodied morph of Poecilia mollies. The rounded body and shortened spine create a compact profile that differs from normal molly strains. It can appear in many colors, including black, white, orange, marble, and dalmatian forms. Males have a gonopodium, while females are larger and rounder.

Behavior & temperament

Balloon Mollies behave like other mollies but are less athletic because of the short body shape. They need hard, alkaline, clean water, vegetable-rich food, and stable filtration. Keep with peaceful livebearers or calm community fish, avoid fin nippers, and avoid very strong current. The body form is a welfare-sensitive trait, so conservative care is important.

Diet & feeding

Balloon Mollies are omnivorous grazers with a strong need for plant matter. Feed quality livebearer flakes or small pellets, spirulina foods, algae wafers, blanched greens, daphnia, brine shrimp, and occasional bloodworms. Do not rely on protein-heavy foods alone.

Behind the name

Balloon describes the rounded domestic body shape; molly is the aquarium name for several Poecilia livebearers.
