The Large Swordtail is a robust, active livebearer known for its elongated “sword” tail and vibrant coloration. It thrives in spacious, well-aerated aquariums with moderate water movement and plenty of open swimming areas mixed with plants for cover. Males can be territorial, so a ratio of one male to several females helps maintain peace. These hardy fish prefer slightly alkaline, moderately hard water and are well-suited for community tanks with other peaceful species. They are omnivores that enjoy a varied diet of flakes, pellets, and occasional live or frozen foods. Regular water changes, a good filter, and stable water conditions will keep them healthy and colorful.
