How do you take care of molly fish?

1. Water quality: Water quality is the most important factor in keeping mollies healthy. Mollies prefer hard, alkaline water with a pH of 7.5-8.5 and a hardness of 10-20 dGH. The temperature should be kept between 75-80 degrees Fahrenheit. Mollies are sensitive to changes in water temperature, so it is important to acclimate them slowly when adding them to a new tank.

2. Filtration: Mollies are active fish that produce a lot of waste, so it is important to have a good filtration system in place. A sponge filter or a power filter with a sponge pre-filter is a good choice for a molly tank.

3. Tank size: Mollies are relatively small fish, but they need a tank that is at least 20 gallons in size. A larger tank will give mollies more room to swim and reduce stress.

4. Decorations: Mollies appreciate plants in their tank for cover and spawning. Some good choices include hornwort, java moss, and anacharis.

5. Diet: Mollies are omnivorous fish and will eat a variety of foods. They can be fed flake food, pellets, or live food such as brine shrimp or bloodworms. It is important to feed mollies a high-quality food that is rich in nutrients.

6. Breeding: Mollies are livebearers, which means they give birth to live young. Mollies can breed year-round, but they will reproduce most successfully in the spring and summer when the water temperature is higher. To encourage breeding, keep mollies in a tank with plenty of plants and provide them with a high-quality diet.

7. Common diseases: Mollies are susceptible to a variety of diseases, including ich, fin rot, and velvet. It is important to quarantine new fish before adding them to your tank and to treat any diseases promptly.
