Green Sailfin Molly

Green sailfin mollies are the closest relatives to the original sailfin mollies of Central America, and males can be quite aggressive. To keep peace in the aquarium, or at least peace for a lone female, two females to one male is recommended, or a small school.

Quick Facts

Care Guide

Tank setup: Give sailfins hard, alkaline water with plants, open swimming space and good filtration. Aquarium salt is optional; they also do well in brackish tanks.

Feeding: Mollies graze on algae, so feed a quality flake that includes vegetable matter once or twice a day. They also enjoy algae wafers and frozen brine shrimp.

Tankmates: Mollies get along with most peaceful community fish that like similar hard water, such as platies, swordtails, guppies, danios, rainbowfish, corydoras and plecos. Avoid fin-nippers and soft-water specialists. Keeping more females than males keeps any one female from being harassed.

Good to know: Male sailfins raise their tall dorsal fin to show off to females and rival males. Their sails grow fuller as they mature, so juveniles may not show a full sail yet.
