Hardy livebearers for the first tank — and like guppies, they will multiply.
Quick answer: Black 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 Black 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 We do not publish variety-specific temperament, lifespan or weight numbers that we cannot source.
Water and tank: flexible but not filthy
Platies: 20–26°C (68–78°F), pH 6.8–8.0, standard community hardness. Mollies: warmer, 24–28°C, and genuinely preferring hard, slightly alkaline water — soft acidic water slowly weakens them; a little aquarium salt is traditional and harmless in a species tank. Tank floor: 60 cm for platies, 75–90 cm for mollies, planted edges with open swimming space. Both need zero ammonia and nitrite and weekly partial changes — 'hardy' means they survive mistakes longer, not that mistakes are free.
Feeding: omnivores with a sweet tooth for greens
Quality flake or micro-pellet as the base, plus blanched zucchini, spirulina flake or shelled peas several times a week — mollies in particular graze algae and get constipated on protein-heavy diets alone ('shimmying' is often a constipation-and-water-quality sign, not a mystery disease). Small frozen foods as treats. Feed what they finish in a minute or two; overfeeding pollutes small tanks fast.
