Sexing

Feeding regime

 * Feed once or twice a day.

Environment Specifics

 * 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.

Behaviour

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

Identification

 * 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.
