Wild specimens of this species look similar to those of P. latipinna (Sailfin Molly). However, Yucatan Molly is larger, and has a fuller sail-like dorsal fin, with a greater number of fin rays (18 or 19 as opposed to 14). Ease of hybridization between this species, P. latipinna, and/or P. sphenops (Sphenops Molly) has resulted in a spectacular range of aquarium varieties.
