Species Summary

Molly fish are a staple of freshwater fishkeeping, known for their low-maintenance care requirements and wide selection of possibilities. The most common varieties of molly fish typically available for aquariums are the common molly, the black molly, the white molly fish, the sailfin molly and the Mexican molly.

Molly fish care requires a spacious tank with temperature-controlled water to avoid sudden and dramatic temperature fluctuations. Tanks should be large enough to allow the mollies to swim freely and grow to a size of around 10 inches (25 cm).

They are herbivorous fish, so they should be fed a variety of live and frozen foods. Aside from tank setup, lifespan, breeding, and feeding details, you must also consider molly fish facts such as appearance, behavior, lifespan, and diet.

Appearance

Mollies are common aquarium fish that can be found in a range of different colors, such as silver, black, or white. They typically have a silvery or black body with a prominent dorsal fin resembling a sail. Red mollies have dark orange or red bodies with black fins.

Some mollies have been selectively bred to create different color variations such as black, dalmatian, lyretail, balloon, gold dust, marble, platinum, and creamsicle. Mollies can reach up to 4–5 inches (10–13 cm) in length and are often kept in aquariums.
