Additional names

Molly, Sailfin Molly, Lyretail Molly


The male has a gonopodium fin and smaller than the female who will have a rounder larger body shape.

Tank compatibility[edit]

A relatively peaceful fish, however, the male will chase the females and therefore they must be kept in the ratio of one male per two/three females. They should only be kept with similar sized robust, but not aggressive, fish.


Will graze on algae as well as accepting most foods including pellet and flake, as well as spirulina, brine shrimp and bloodworm.

Feeding regime[edit]

Feed once or twice a day.

Environment specifics[edit]

They prefer a spacious tank with open swimming space as well as hiding places. They do best at lower-end brackish rather than freshwater. Keep them in salt-free water can lead to the Shimmies. Can tolerate sea water.


A generally peaceful fish who has been known to bully other livebearers. Are also known to eat their own fry.


Many colour variations of this fish are now available, and they will crossbreed with other Molly species. They are generally elongated, with strong lateral compression. The outstanding feature of this fish is the dorsal fin of the male, which he can extend out like a sail.
