Molly fish care guide
Mollies are livebearers that do well in neutral to hard water.
Tank size and setup
At least 20 gallons for a small group. Heater (75–80 °F) and filter. They like plants and open space. Keep water parameters stable; neutral to slightly hard, pH around 7–8, works well.
Feeding and breeding
Omnivores: quality flake or pellet plus veg and occasional live/frozen. Do not overfeed. They breed readily; plan for fry or keep single-sex groups. Good tank mates: platies, guppies, tetras, corydoras. See community tank fish. Track with App-aquatic.
Quick takeaways
- 20+ gallons; neutral to hard water, warm.
- Varied diet; they breed easily; peaceful with community fish.
