The Gold Sailfin Molly (Poecilia lastipinna morph) is a bright, active livebearer known for its metallic gold coloration and impressive sail-like dorsal fin. Males are especially eye-catching as they display their large dorsal fins while swimming and courting females.

Tank Setup
Gold Sailfin Mollies do best in a planted aquarium with open swimming space, stable water parameters, and strong filtration. Mollies can be active and produce a moderate amount of waste, so good filtration and regular maintenance are important.
They prefer harder, more alkaline water and may benefit from slightly brackish conditions in some setups, but they can thrive in well-maintained freshwater aquariums when water quality is stable.
Diet & Feeding
Gold Sailfin Mollies are omnivores that enjoy grazing on algae and biofilm. Offer a varied diet of quality flakes, vegetable-based pellets, spirulina foods, algae wafers, and occasional frozen or live foods such as brine shrimp and bloodworms.
Supplementing with plant-based foods such as spirulina, algae-based foods, and blanched vegetables like zucchini or spinach can help support healthy digestion and color.
Best Tankmates
Gold Sailfin Mollies are peaceful community fish and do well with other livebearers such as platies, guppies, and swordtails. They can also be kept with peaceful community fish such as Corydoras, rasboras, and larger peaceful tetras.
Avoid aggressive fish, fin-nippers, or species that prefer very soft, acidic water.
Breeding Information
Gold Sailfin Mollies are livebearers, meaning females give birth to free-swimming fry instead of laying eggs. Females may give birth every 28–40 days, with broods ranging from 20–100 fry depending on age, size, and condition.
For best results, keep mollies in groups with a ratio of one male to two or three females. Dense plants, floating plants, or a breeding box can help protect fry from being eaten.
Fun Fact
The Gold Sailfin Molly is prized for its brilliant gold body and oversized dorsal fin, which can wave like a flag as the fish swims through the aquarium.
