🐟 Molly Fish Care Guide
(Poecilia sphenops, Poecilia latipinna, Poecilia velifera)
Mollies are active, social, and relatively hardy freshwater fish that come in a wide variety of shapes and colors — including Black, Dalmatian, Sailfin, Balloon, Leopard and Lyretail types. They're livebearers and do well in community tanks or species-only setups.
🏠 Tank Setup
Tank Size:
Minimum: 20 gallons for a small group
Larger mollies (like Sailfin): 30+ gallons
Water Parameters:
Temperature: 74–80°F (23–27°C)
pH: 7.5–8.5 (prefer alkaline water)
Hardness: 12–30 dGH (like hard water)
Ammonia/Nitrites: 0 ppm
Nitrates: < 40 ppm
Filtration:
Use a reliable filter with moderate flow. Mollies are messy and benefit from extra filtration.
Substrate & Décor:
Sand or gravel
Live plants (Anubias, Java fern, Vallisneria)
Driftwood, rocks, and caves for exploration
Lighting:
Moderate lighting; beneficial for plant growth and fish coloration
🧑‍🤝‍🧑 Tank Mates
Peaceful Companions:
Guppies, platies, swordtails
Corydoras catfish
Tetras (non-nippy types)
Snails and shrimp (if tank is well-planted)
Avoid:
Betta fish (possible aggression)
Fin-nipping barbs
Larger, aggressive cichlids
🍽️ Feeding
Diet: Omnivorous (with a herbivorous preference)
Feed a mix of:
High-quality flakes or pellets
Blanched vegetables (zucchini, spinach, cucumber, peas)
Algae wafers
Frozen/live foods (brine shrimp, daphnia, bloodworms — use sparingly)
Feeding Schedule:
1–2 times per day; feed only what they can eat in 2–3 minutes
👶 Breeding & Sexing
Livebearers:
Mollies give birth to 20–100 fry every 30–45 days
Sexing Mollies:
Males: Smaller, slimmer, gonopodium (pointed anal fin)
Females: Larger, rounded belly, fan-shaped anal fin
Breeding Tips:
Keep more females than males (1:2 or 1:3 ratio)
Use dense plants or breeder boxes to protect fry
If you want to raise fry, transfer them to a separate nursery tank
🧽 Maintenance
Weekly Tasks:
25–50% water change
Vacuum substrate
Monitor water parameters
Monthly Tasks:
Rinse filter media in old tank water (not tap)
Trim and clean plants if needed
⚠️ Common Issues
Overcrowding:
Mollies are active and need space — overcrowding leads to stress and aggression
Fry explosion:
Mollies breed often — if not separated, the tank can overpopulate quickly
Health Problems:
Ich (white spots)
Fin rot
Livebearer disease (common in poor-quality or balloon mollies)
Tip: Adding aquarium salt (1 tsp per 5 gallons) can help reduce stress and support gill function — especially beneficial for mollies.
💡 Quick Tips for Success
Mollies thrive in slightly brackish water, though it's not required unless breeding or recovering from illness
Always cycle your tank before adding mollies — they are sensitive to ammonia spikes
Balloon mollies are genetically modified and may have health issues — avoid them if you want long-lived, robust fish
❤️ Final Thoughts
Mollies are energetic, easy to care for, and come in a stunning array of colors and fin shapes. With proper care, a balanced diet, and a well-maintained tank, these friendly fish can thrive for 3–5 years — and may even surprise you with baby fish!
