Setting Up the Tank for Mollies
To keep mollies healthy, you need a good tank setup. Here are some important things to remember:
| Requirement | Details |
|---|---|
| Tank Size | At least 20 gallons for a small group of mollies. |
| Water Temperature | Keep water between 72°F and 78°F (22°C-26°C). |

| Filtration | Use a good filter to keep water clean. |

Water Quality Is Very Important
Mollies produce waste that can dirty the water quickly. A good filter is a must. Change 25% of the water every week. This keeps the tank clean and fish healthy. Avoid sudden changes in water. Stability helps fish stay strong.
Feeding Your Molly Fish
Mollies eat many kinds of food. Give them a mix for best health. Here are some food types to use:
- High-quality flake food for livebearers
- Frozen or live foods like brine shrimp and daphnia

Feed them small amounts two to three times a day. Do not overfeed. Leftover food can pollute the tank.

Choosing Tank Mates for Mollies
Mollies are peaceful and can live with many fish. But some fish may bully them. Avoid very small or very aggressive fish. Also, do not mix mollies with fish needing soft or acidic water. Mollies like harder, alkaline water.
Good tank mates include:
- Platies
- Guppies
- Corydoras catfish
- Snails and shrimp
Understanding the Salt Myth
Some people add salt to molly tanks. They think it helps fish health. But salt is not always needed. Good tank care is more important. This means:
- Regular water changes
- Good aeration
- Proper filtration
Salt can hide poor water conditions. It should not replace good care. If you use salt, do it carefully and in small amounts.

Breeding Mollies
Mollies are livebearers. They give birth to live babies called fry. If you have males and females together, expect fry soon. Mollies can have many babies at once.
Fry are very small and can be eaten by adult fish. You may need a separate tank for fry. In this tank, feed them tiny foods like infusoria. This helps fry grow strong and healthy.

Mollies are hardy fish but can get sick. Watch for signs like:

Keep water clean and stable to avoid sickness. Quarantine new fish before adding them. This prevents disease spread.
