Black Molly — one of the molly fish varieties owners search for by name.
Black Molly is one of the molly fish varieties people look up by name. This page answers the questions owners actually type about black molly, then points you to the sourced molly fish care guidance that applies to every variety.
Livebearing, algae-grazing and opinionated about water — the fish that teaches keepers what hard, clean, slightly salty water really means.
Quick answer: Black 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 Black 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 We do not publish variety-specific temperament, lifespan or weight numbers that we cannot source.
A group of mollies wants 75+ liters (20+ gallons) — they are active and messy. Temperature 24–27 °C, pH 7.5–8.5, hard water. A small dose of aquarium salt is a traditional, well-tolerated addition for mollies specifically; do not add salt to tanks with live plants or scaleless tank mates.
Mostly plants and algae with a quality flake or pellet base — they are heavily herbivorous for livebearers. Offer blanched zucchini, peas and spinach regularly; the algae-grazing reputation is real, and a molly without greens is a molly with a compromised immune system.
