The Sailfin Molly (Poecilia latipinna) is a hardy, peaceful livebearer best known for the males’ towering “sailfin” dorsal. Color phases we carry rotate through the classic palette — silver, dalmatian, marbled green, and gold — so each shipment is a colorful, beginner-friendly addition to a community tank. Note that mollies thrive inhard, alkaline waterand can even adapt to brackish setups. Browse our other freshwater livestock to round out a compatible community.
Care Guide
- Minimum tank size:30 gallons. Sailfin Mollies are bigger than common short-finned mollies and need swimming room — long tanks beat tall ones.
- Temperature:72–82°F (22–28°C).
- pH:7.5–8.5 — they thrive in hard, alkaline water. Avoid acidic blackwater setups.
- Hardness:Moderately hard to hard (10–25 dGH). A pinch of aquarium salt or marine salt is welcomed but not required.
- Diet:Omnivore leaning herbivore. Offer a high-quality tropical flake daily, plus blanched zucchini, spirulina, or algae wafers 2–3 times a week. Bloodworms and brine shrimp work as treats.
- Stocking ratio:Keep more females than males (2–3 females per male) to spread out the male’s attention and prevent harassment.
- Livebearer:Mollies are prolific live-bearers. If you don’t want fry, plan to rehome them or expect natural attrition in a community tank.
- Brackish capable:Sailfins are one of the most salt-tolerant livebearers and can be slowly acclimated up to low-end brackish (SG 1.005–1.012) if desired.

FAQ
Will I get fry?
Almost certainly. Mollies are livebearers and breed readily in good conditions. Hidden fry survive better in heavily planted tanks; otherwise most are eaten by tank mates and adults.
Do I need salt in the water?
No — Sailfin Mollies do fine in straight fresh water as long as it’s hard and alkaline. A pinch of aquarium salt won’t hurt and can help with stress, but it’s optional.
Why do my mollies look pale or have clamped fins?
Usually a water quality or hardness issue. Mollies struggle in soft, acidic water — test pH and GH and adjust toward 7.5–8.5 / 10–25 dGH. Stable parameters fix most “molly diseases” before they start.
Can I pick the colors?
We rotate stock by what arrives from our suppliers — silver, dalmatian, marbled green, and gold are common. Come in and we’ll show you what’s swimming in the display.
