The Red Wag Swordtail demonstrates a classic color combination notable among the widely bred color varieties of the Xiphophorus helleri Swordtail. The bold color combination of red and black gives the Red Wag Swordtail a sophisticated appearance. The Swordtail is perhaps the quintessential community aquarium fish. The time-tested popularity of the Swordtail can be attributed to its ease of care, peaceful temperament, and wonderfully diverse fin and color varieties. The most common Swordtail varieties include: Red Velvet, Marigold, Black Nubian, Pineapple, and Neon Swordtail. The male Swordtail is especially prized for its namesake feature, the showy extension on the lower part of its tail resembling a sword.
The Red Wag Swordtail requires an aquarium of at least 20 gallons that is well planted with plenty of room for swimming. Because of its peaceful nature, the Red Wag Swordtail is well suited for the community aquarium. However, the male Red Wag Swordtail can demonstrate territorial aggression towards other male Swordtails so care should be taken when housing more than one male. Also, the Red Wag Swordtail is an accomplished jumper, so be sure to provide a secure cover for the aquarium.
