Add a vibrant pop of contrasting colour and dynamic movement to your aquarium canopy. The Sanke Koi Swordtail is a premium, selectively bred variation of the classic Central American swordtail. It combines the brilliant, highly sought-after aesthetic of pond koi with the effortless, beginner-friendly care of a community livebearer.

This species is highly celebrated for its dramatic sexual dimorphism. Mature males develop a spectacular, regal extension on the lower ray of their tail fin—forming the signature "sword" that gives the species its name—which they use in captivating, backward-swimming courtship displays to attract mates. Females are larger, rounder, and while they lack the long sword, their striking tri-colour patterns make them equally breathtaking to behold.

Because they are bred in captivity, they are highly adaptable to standard tap water parameters. They spend most of their time actively patrolling the mid-to-upper levels of the water column, adding incredible energy to your aquascape while acting completely safe around live aquatic plants.
