This small, peaceful species grow to around 3-4 inches, and adapt well to a variety of water conditions.
The ideal tank conditions are: a minimum tank size of 20 gallons, and warm water with a pH between 7.0-7.8.
Mollies are omnivorous, and will require a diet of both plant and animal food.
Interestingly, they are livebearers, meaning they give birth to their young live, rather than lay eggs. Mollies are very easy to care for, but they also breed very easily, so if you’re a beginner you might want to keep just a single sex.
