Poecilia latipinna

About This Species

Basic Description

The Sailfin Molly, also known as the Common or Black Molly, is an active and brightly colored fish from North America. As omnivores, they enjoy a mixed diet of flakes, vegetables, and other fish foods. They are social creatures that should be kept in small groups and are often seen swimming near the top of the tank. While beautiful, their care is considered of medium difficulty. They are known for their long fins and for being very active swimmers, making them a lively addition to an aquarium. They are also known to jump, so a lid is recommended.

Detailed Description

Originating from North America, the Sailfin Molly is a popular livebearer that thrives in either freshwater or brackish conditions with low water flow. They require hard, alkaline water to flourish. These are very active, fast-swimming fish that occupy the top and middle water columns. This high activity level contributes to them being potential tank jumpers. As omnivores, they have a beneficial role in the aquarium's ecosystem by acting as algae cleaners and biofilm consumers. While their breeding is considered easy, overall care is rated as medium difficulty due to specific water parameter needs and their bioload contribution from a medium metabolism and waste production.

Scientific Description

Poecilia latipinna is a species of fish in the family Poeciliidae, native to North America. It inhabits low-flow freshwater and brackish systems, requiring alkaline conditions and high water hardness. This species is an omnivore with a diet that includes algae and biofilm, classifying it as an environmental interactor that helps clean surfaces. It is a shoaling fish with a high activity level. Physiologically, it has a medium metabolic rate, oxygen consumption, and waste production, resulting in a moderate bioload factor. It is noted for distinct social characteristics such as bright coloration and long finnage, and its reproductive process is considered easy under appropriate conditions.
