Sunset Red Sailfin Molly – Poecilia latipinna
The Sunset Red Sailfin Molly, scientifically known as Poecilia latipinna, is a colorful freshwater livebearer known for its warm red, orange, and golden coloration. Mature males may develop a large, sail-like dorsal fin that creates an impressive display when swimming or interacting with other mollies.
Sunset Red Sailfin Mollies are active social fish that do best in a spacious, well-filtered aquarium with stable water conditions. They can be kept in freshwater, although mollies generally prefer moderately hard, mineral-rich water. They are best housed with peaceful community fish that share similar water requirements.

Feeding
Sunset Red Sailfin Mollies are omnivores and should receive a varied diet. Feed a quality tropical flake, small pellet, or livebearer food as the primary diet. Include foods containing spirulina, algae, or other plant-based ingredients to support digestion and overall health.
Their diet may also be supplemented with frozen or live foods such as brine shrimp, daphnia, bloodworms, or mysis shrimp. Feed only what the fish can consume within a few minutes and remove uneaten food to protect water quality.
Compatible Tankmates
- Other mollies
- Platies
- Swordtails
- Larger peaceful tetras
- Danios
- Peaceful rainbowfish
- Corydoras suited to similar water conditions
- Peaceful plecos and compatible bottom dwellers
Avoid keeping Sunset Red Sailfin Mollies with aggressive fish, persistent fin nippers, or species requiring very soft and acidic water. Compatibility depends on aquarium size, water parameters, individual temperament, and group structure.
Keeping Sunset Red Sailfin Mollies Together
Sunset Red Sailfin Mollies are social and are generally best kept with other mollies. When keeping males and females together, maintain more females than males to reduce persistent attention toward individual females.
A ratio of approximately one male for every two or three females can help distribute breeding behavior. Mollies reproduce readily, so keepers should prepare for fry when both sexes are present.
Sunset Red Sailfin Molly Care Tips
- Maintain stable, moderately hard water
- Avoid keeping mollies in extremely soft or acidic conditions
- Provide open swimming areas and planted cover
- Feed foods containing algae, spirulina, and plant-based ingredients
- Keep more females than males in mixed groups
- Provide dense plants if you want fry to have places to hide
- Monitor ammonia, nitrite, nitrate, pH, hardness, and temperature
- Perform regular water changes to maintain good water quality
Important Aquarium Care Note
Mollies are often sold as beginner fish, but they may struggle when kept in unstable, very soft, or poorly maintained water. Good filtration, consistent maintenance, suitable mineral content, and stable water parameters are important for long-term health.
Aquarium salt is not automatically required for Sunset Red Sailfin Mollies. Their mineral needs are better addressed by maintaining suitable hardness and stable water chemistry. Do not add salt to a community aquarium without considering the needs of every fish, plant, shrimp, and snail in the setup.
Frequently Asked Questions
How large do Sunset Red Sailfin Mollies get?
Sunset Red Sailfin Mollies can reach approximately 4 to 6 inches, depending on genetics, sex, diet, aquarium size, and overall care.
Are Sunset Red Sailfin Mollies peaceful?
They are generally peaceful community fish. Males may compete with one another or persistently pursue females, so adequate space and a suitable male-to-female ratio are important.
Do Sunset Red Sailfin Mollies need salt?
Not necessarily. They can live in freshwater when provided with stable, moderately hard, mineral-rich water. Salt should not be added automatically, especially in aquariums containing salt-sensitive species.
What do Sunset Red Sailfin Mollies eat?
They eat quality flakes, pellets, algae-based foods, spirulina foods, and occasional frozen or live foods such as brine shrimp and daphnia.
Can Sunset Red Sailfin Mollies live with other mollies?
Yes. They can be kept with other compatible molly varieties in an appropriately sized and well-maintained aquarium.
Do Sunset Red Sailfin Mollies give birth to live babies?
Yes. Mollies are livebearers, meaning females give birth to free-swimming fry. They may reproduce frequently when males and females are kept together.
How can you tell male and female mollies apart?
Males have a narrow, pointed reproductive fin called a gonopodium. Females have a broader, fan-shaped anal fin and generally develop fuller bodies.
Will every Sunset Red Sailfin Molly look the same?
No. The amount of red, orange, gold, and darker coloration can vary between individual fish. Male dorsal-fin size and patterning may also vary.
