What to know before you buy.
The Sailfin Molly is a spectacular sight, with males possessing a huge, sail-like dorsal fin that they use for display. They are larger than common mollies and require a spacious tank with hard, alkaline water, and some even benefit from a small amount of salt. They are active algae grazers and peaceful community residents.
