LiveAquaria Assorted Swordtail Fish
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 Wag, 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 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 Swordtail is well suited for the community aquarium. However, the male Swordtail can demonstrate territorial aggression towards other male Swordtails so care should be taken when housing multiple males.

These Swordtails are vibrant and active. I have a 20-gallon tank with a mix of Red Velvet and Marigold varieties. They swim freely and don’t stress the other fish. The colors are bright and the males show off their tail fins beautifully.

Great addition to my community tank. The fish are easy to care for and stay calm with other species. I noticed one male was slightly aggressive toward another, so I now keep only one male. Otherwise, they’re lovely.

I bought the assorted pack and it’s exactly as described. The Red Wag and Pineapple varieties stand out in the tank. The fish adapt quickly and are active throughout the day. Very satisfied with the purchase.
