Quick answer: Sailfin Molly is a variety of molly fish. Everything on this page is molly fish-level guidance — we do not invent variety-specific numbers.
The care below is molly fish-level guidance from our species hub, sourced to Merck Veterinary Manual — Aquarium Fish: Husbandry and Diseases and RSPCA — Aquarium fish care advice. It applies to Sailfin Molly exactly as it applies to every other molly fish variety. We do not publish variety-specific temperament, lifespan or weight numbers that we cannot source.
Common mollies reach 8–10 cm (3–4 inches); sailfin mollies up to 13 cm (5 inches). Balloon varieties stay smaller but carry a shortened, curved spine — a body shape we do not recommend breeding or buying.
3–5 years with hard, clean water and no constant breeding. Soft or acidic water, overbreeding and small tanks are the three things that shorten molly lifespans the most.
