The Twintail Swordfish is a striking and active livebearer known for its elegant double tail and extended lower fin “sword.” It thrives in a peaceful community aquarium with plenty of swimming space and some plants for cover. Ideal water parameters include slightly alkaline, moderately hard water, and warm temperatures. Males can be territorial, so keeping more females per male helps reduce aggression. They are omnivorous and accept flakes, pellets, and live or frozen foods. Regular water changes and a well-filtered tank are essential to keep them healthy and vibrant.
