Quick answer: Sailfin molly is a variety of mollies & platies. Everything on this page is mollies & platies-level guidance — we do not invent variety-specific numbers.
The care below is mollies & platies-level guidance from our species hub, sourced to Merck Veterinary Manual — Exotic & Laboratory Animals: Aquarium Fish and RSPCA — Aquarium fish advice. It applies to Sailfin molly exactly as it applies to every other mollies & platies variety. We do not publish variety-specific temperament, lifespan or weight numbers that we cannot source.
Breeding: the population math
Females carry fry for about 4–6 weeks and can store sperm, producing several broods from one mating — a single visiting male can stock your tank for a year. Broods of 10–40 fry arrive monthly per female in good condition. Adults eat fry; dense plants (hornwort, java moss) raise survival naturally, or breed in a species tank with a breeder box. If you cannot rehome fry, keep one sex — and know that 'all female' purchases at pet stores often include one already-fertilized fish.
Health and tank mates
Watch for: shimmying (usually water quality or cold — test before medicating), white spot (ich — standard treatment, follow product temperature guidance), fin rot from poor water, and the livebearer classic, internal parasites in new imports (wasting despite eating — treat the whole tank). Good companions: tetras, corydoras, guppies (watch hybridizing with endler types), rasboras. Avoid large or fin-nipping fish — sailfin molly fins and platy tails are targets.
