Sailfin Molly

Key differences: While some Sailfin Mollies can be black, they are distinguished by their significantly larger and more elaborate dorsal fin, which can extend almost the entire length of their back, especially in males. Black Mollies typically have a more standard-sized dorsal fin.
Lyretail Molly
Poecilia sphenops var. Lyretail
Key differences: Lyretail Mollies, regardless of color, are characterized by their distinctive lyre-shaped caudal fin, where the outer rays are elongated. Black Mollies have a rounded to slightly truncated caudal fin.
Black Skirt Tetra
