Tiger Swordtail Fish
The Tiger Swordtail (Xiphophorus hellerii) is a striking freshwater livebearer known for its golden-yellow body, bold black tiger striping, and the classic sword-shaped tail extension found on males. Active, peaceful, and hardy, this swordtail variety adds constant movement and eye-catching contrast to freshwater community aquariums.
Tiger Swordtails are a great choice for both beginner and experienced fishkeepers. They do well in planted aquariums, livebearer tanks, and peaceful community setups with other similarly sized fish.

Tank Setup
Tiger Swordtails do best in a well-filtered freshwater aquarium with open swimming space and stable water parameters. Live or artificial plants provide cover, help reduce stress, and give fry hiding places if breeding occurs.
For best results, keep swordtails in groups with more females than males. A good ratio is one male with two to three females to help reduce stress on females and encourage natural behavior.
Tank Mates
Tiger Swordtails are peaceful community fish and do well with other livebearers and non-aggressive freshwater species. Suitable tank mates may include platies, mollies, guppies, peaceful tetras, rasboras, danios, corydoras, and other peaceful catfish.
