Habitat Setup

Recreate their natural freshwater environment with:

• Sand or fine gravel substrate

• Dense live plants and floating plants for cover

• Open swimming space

• Moderate water flow

Golden Mollies enjoy hiding spots and plants to rest near, especially when breeding.

️ Feeding

Golden Nugget Mollies are omnivorous:

• High-quality flake or pellet foods

• Frozen or live foods (brine shrimp, daphnia, bloodworms)

• Occasional vegetable matter (blanched spinach, zucchini, spirulina flakes)

Feed 1–2 times daily, adjusting portions to avoid overfeeding.

Tank Mates

Golden Mollies are peaceful and social, best kept in groups of 4 or more.

Ideal companions:

• Guppies

• Platies

• Corydoras

• Small peaceful barbs

Avoid:

• Aggressive fish

• Slow-moving species that may be bullied

⚠️ Behavioral Note: Males may display minor chasing or fin-flaring in groups, which is normal social hierarchy behavior.

Breeding

Golden Mollies are livebearers and breed readily in aquariums.

• Gestation lasts about 24–28 days
