Body Coloration: The Marigold Wag Swordtail boasts a brilliant marigold-yellow to orange body with intense coloration. The term "Wag" refers to the solid black color on the fins, which creates a striking contrast with the bright body.
Fins: The dorsal, caudal (tail), and sometimes the pectoral fins are typically black, giving the fish its "Wag" name.
Sexual Dimorphism: Males have the signature sword-like tail extension on the lower part of their caudal fin, while females lack this extension and are generally more rounded in shape.
Size:
Males can grow up to 5-6 inches (12-15 cm) including the tail, while females are slightly smaller, around 4-5 inches.
Lifespan:
Marigold Wag Swordtails have a lifespan of 3-5 years, though with excellent care, they may live longer.
Behavior:
Peaceful and Active: These swordtails are active swimmers and generally peaceful, making them well-suited to community tanks. Males can occasionally become territorial, particularly in smaller tanks, but this behavior is typically mild.
Livebearers: Like all swordtails, Marigold Wags are livebearers, meaning females give birth to live fry every 4-6 weeks under good conditions.
Habitat & Tank Requirements:
Tank Size: A minimum of 20 gallons is recommended for swordtails, as they are active swimmers and need plenty of space.
Water Parameters: They thrive in slightly alkaline water with a pH of 7.0-8.3 and temperatures between 72-82°F (22-28°C).
Aquarium Setup: Provide a well-planted tank with open swimming areas. Plants and decorations offer hiding spots, especially for fry.
Diet:
Omnivores: Marigold Wag Swordtails do well on a varied diet, which includes:
High-quality flakes or pellets.
Vegetables: Blanched spinach, peas, and other plant-based foods.
Protein: Live or frozen foods like brine shrimp, bloodworms, and daphnia.
Breeding:
Prolific Breeders: Females can give birth to 20-50 fry every 4-6 weeks. A breeding box or dense planting can help protect the fry from being eaten by adult fish.
Keeping a 1 male to 2-3 females ratio is recommended to prevent males from stressing females.
Tank Mates:
The Marigold Wag Swordtail is compatible with other peaceful community fish, including:
Platies
Mollies
Guppies
Corydoras
Tetras
Health and Care:
These fish are hardy but can be prone to common freshwater diseases like Ich or fin rot if water quality is poor. Regular water changes and a good filtration system are important for maintaining their health.
Temperament:
Marigold Wag Swordtails are generally peaceful, but males may display mild aggression or territorial behavior, especially towards other males. Keeping them in a spacious tank with plenty of hiding spots can reduce stress.
Hardiness:
As a robust species, they are beginner-friendly, adapting well to a range of tank conditions as long as the water is clean and well-maintained.
