Females have a fuller body and rounded anal and dorsal fins.
This fish, also called the Short-Finned Molly, will behave most naturally if there are live plants in the tank, and does best at the warmer range in the aquarium with a little aquarium salt added. It's usually a good idea to provide more females than males in the aquarium. Obviously, selective breeding in the fish farms has greatly reduced the price of this fish, besides producing Lyre-Tailed varieties. Mollies are notorious for parasite problems, so aquarium salt is a definite plus. Be sure to stop by our clearance page for a full listing of current closeout and clearance items.
