Description
The Molly, specifically the Short-finned Molly (*Poecilia sphenops*), is a popular and hardy livebearer known for its peaceful nature and adaptability. Originating from Central and South America, they thrive in community tanks with proper water conditions, often preferring harder, alkaline water. They are omnivores, primarily feeding on algae and plant matter, making them good algae eaters.
