The fish, up close
The Sailfin Molly, scientifically known as Poecilia latipinna, is a peaceful and attractive freshwater fish species that is popular among aquarium hobbyists. These fish are named for their distinctively large and showy dorsal fins, which can be extended and raised like a sail. Sailfin Mollies come in a variety of colours, including black, orange, silver, and gold, and they have a slender body shape with a slightly upturned mouth. They are known for their lively and active swimming behaviour, making them a delightful addition to community aquariums.
Care guide
Use these notes to shape a setup around the fish, then speak with our team about the tank you have in mind.
Plan your setupBehaviour
These fish are generally peaceful and do well in community aquariums with other peaceful fish species. Male Sailfin Mollies can sometimes display territorial behaviour towards each other, especially if there are limited hiding spots or females present. They are active swimmers and enjoy exploring their environment.
Tank planning
Sailfin Mollies thrive in well-maintained aquariums with stable water parameters. They prefer slightly brackish water conditions, so adding a small amount of aquarium salt can benefit their overall health. Regular water changes and monitoring of water quality are essential to keep Sailfin Mollies healthy and vibrant.
